Never hated Eureka. I really disliked Pagos as it was and extremely boring step. Pyros introduced the logograms which made it quite fun and interesting (the map was also good and Bunnies) and then Hydatos was the victory lap with the BA waiting you at the end if you wanted to do a nice and bit hard content.

Now as for the rest of your post. Eureka is fine and needs no more buffs. You can be done with it in a week or two which is quite reasonable.
