"The game wasn't designed to have multiple action bars."
This is a very bold statement:) Perhaps, developers tried to figure out one time, why WoW is so successful? Because World of Warcraft is almost the only one game in which
you do not fight against the User Interface but just the game's world. Imagine my disappointment when I can't add a skill to the ability bar because of no room there and no option to extend it

). I also tried to install LUI, but I have transparent health, mana & energy bars what looks not good and irritates me if I have some errors. I have spent about one hour to configure it and fix it but with no success (even reinstalled the add-on). Then, I found the solution on a forum - install
bandit interface xD What a wonderful workaround xD I also wanted to bind a key shortcut eg:
alt-9. It turns out I can bind only
alt or only
9 but not the combination. I can't treat ESO as my main MMO until developers understand the phenomenon of WoW mechanics. From some reasons I do not want to play WoW but I have a good alternative - ArcheAge.
