My thoughts on the EoC have been changing quite a bit.
First reaction: hated it. tried beta and started to learn all bout this update and sort of looked forward to it.. then it was released and I enjoyed it for a while, until i was sick of using abilities constantly. Then i started using momentum for slayer tasks, which made it more enjoyable, but they should still make momentum a little better seeing as it's still not comparable to ability spamming. EoC has been GREAT for skilling though Also dungeoneering is really easy in comparison now. I suggest trying different things and seeing what you can do with your action bar before jumping to bold conclusions.
Most people saying they hate eoc haven't really given it a chance IMO, also if you don't like the action bar why not just use momentum which improves your auto attacks by alot for 20mins,then minimize action bar and almost just like pre-eoc except you hit better,also improved skilling
