I'm not going to spend a lot of time on this topic. This is just a quick post to say I tried it, and I hate it.
Now I hate the vomitous lima bean green DA currently uses, but this is far better than the mess Eclipse offers. Basically you can look forward to a lot of bloat, clunk, and the removal of buttons and features. No access to your portfolio, if you are a core member and made one, The MORE button has been removed. Some of the features it contained have been moved to other places, some are gone. There is no more page customization, html or css. No more custom panels. Can't check who's online. No feedback to the Eclipse Beta devs. Notifications have been changed for the worse. Now instead of the organized system we have, you need to navigate through several sub menues for each separate thing. Personally, I really like the overview I have now on the old site. The search bar is tucked away in a corner and difficult to locate. In fact, that can pretty much sum up most of the new layout and UI. It seems if you pay for CORE membership you will loose most of the benefits you pay for. comments.deviantart.com/1/7725…
The new Eclipse design is a blatant copy of Artstations site design. Theft much? If DA has to resort to design theft to compete, no wonder they never crack down on art theft here.
EDIT: Added some screenshots.
The first one is a screenshot of my DA Eclipse page, the second is my Artation page.
