Yes, I know that StarCraft is a fictional universe, and yes, I know that in this case design>practicality, but still there are some things that puzzle me.
1. Ghost's armour
That (in)famous 'tit armour' for female ghosts is very impractical. Because of its form, bullets and shrapnel will be directed right in the middle of ghost's chest, bouncing off the armoured 'cups'. Armoured vests are flat for a reason. One of those reasons is dispersion of kinetic impulse provided by incoming projectile. And really, have you seen at least one female U.S. soldier in 'tit-shaped body armour'? No. Because it's silly and, in some cases, dangerous for a soldier to wear such crap. The only reason why this approach was used is to attract hormonal teenagers, nothing else. And have you seen that 'spine' section? All I see is assured back trauma.That armoured appendage will do more harm than actual protection.
Male armour is even worse because, being insufficient as it is, it removes shoulder pads. Why? To show off huge shoulders and biceps? Really? I know that some Blizzard artists have a 'hunk' fetish, but come on. As to distribution of armoured elements - it's awful. Thighs - no protection, shoulders - no protection, and half of the torso is not protected too. Do you know what people do when they realise that there's an enemy sniper nearby? They start to ravage the approx. location of that sniper with mortar shells. It means that there will be tons of shrapnel flying around, and ghost 'armour' is useless against it. Even if we talk about small arms fire - look at that exposed belly. And don't tell me this 'but their nano-suits are very durable as is' crap. If their skin suits are so 'durable' - why wear bulky armoured elements on top of it? No. Their suits can make them super-strong and grant them invisibility, but I really doubt that they can provide enough protection. Ehh. Even in mission slides from StarCraft Remastered ghosts depicted wearing full-body armoured suits (except Sarah in her bikini armour). Yet in SCII (Heart of the Swarm) we see a male ghost who goes on a dangerous mission with his shoulders, thighs and belly fully exposed, plus he was uncloaked. And Nova in that scene wears no helmet - only her visor. Because who needs a helmet when you storm a well-fortified secret object full of enemy soldiers in power armour.
Glowing power lines. This element of design really irritates me. A stealthy special agent (usually a sniper) goes on a mission wearing a suit with brightly-glowing power lines all across the body. Show me that genius who invented this crap. It's like waving a huge neon sign 'I'm here, kill me!' over your head, especially in SC universe with its advanced optics and scanners.
Colours. Imagine Nova in a forest. She looks like a big bright target that doesn't blend in at all. Same goes for spectres if they're on a snowy planet. Cloaking device is great, but it can be damaged and it can malfunction. When it happens, a ghost/spectre loses all his/her cloaking capabilities, which, in turn, leads to his/her death (especially if it's a solo mission). I don't believe that it's too difficult to create several camo variants of a ghost skin suit for different environments.
C-10 sniper rifle. I don't know how ammo works in SC universe, but even if it uses some 'nano-powder' or other propelling substance, the barrel length of C-10 is too short to make that rifle a 'sniper' one. A long barrel is needed to allow the gunpowder in a cartridge to burn, 'pushing' the bullet forward. If a barrel is too short, only a part of cartridge's gunpowder will burn - the rest will fly out of the barrel with a bullet, giving that bullet less kinetic energy in the process. Yes, I know that marines use 'rail-assisted' guns, but nothing states that C-10 uses that technology. One more thing - ammo cases. C-10 is semi-auto, which means that cases fly everywhere, especially during heated firefights. It's not a problem for a marine, but it's a problem for a ghost who must be stealthy, leaving no trails. Same goes for female ghosts hair, by the way. Even a single hair can be used as an evidence of for gene-tracking. Yes, female ghosts look pretty with their hair flowing in the wind, but from a practical point of view it's a very bad idea. Now back to C-10. Why does it sound different? When a ghost shots his c-10 in-game, it sounds like a loud high-calibre rifle, but when he uses 'snipe' ability, his rifle suddenly produces Hollywood-like muffled 'ptew!'. What, that ghost uses his rifle without a silencer, and attaches it only when he needs to make a sniper shot? Silly crap. He's a stealthy operative. He can't disclose his position by loud noises, especially when it's a booming 'BAADEW!' of his sniper rifle.
Another weird fact that I red when I looked through SC WIKI. It stated that ghosts are considered 'expendable' and have short life-expectancy. *facepalm* Who wrote that? I really want to see that idiot who thinks that very-rare, psy-gifted agents who possess unique skill sets and who can complete nigh-impossible missions are considered 'expendable'. It reminds me of one episode from SW books where elite clone commandos were used as your typical cannon fodder by idiotic 'commanders', which led to huge losses among those elite soldiers. It's like: 'What? Delta? Order them to direct-assault that fortified position. Yes, that one, full of enemy soldiers with machine-guns, plus mortars and snipers, and give those Delta guys no fire support because they are expendable'.
Again, I understand that 'it's a game', and that design>practicality, but when I see a badly-armoured 'shadow operative' in a white bodysuit with glowing power lines, wearing a mask with glowing lenses and holding a rifle that goes 'BAADEW!' every time it shoots - I facepalm myself because that agent is anything but 'shadowy'.
It's sad that there is no Tosh in Heroes of the Storm. I heard that devs planned to include him, but later his character was scrapped. Nice move, Blizz. Of course it's better to have some deer-lady (Lunara) rather than add an awesome voodoo guy with tons of charisma and interesting personality.
