It would seem it was made like this with the console player's in mind. I'm so sick of the trend with new mmo's and their so called easier to use hotbars. I find it so annoying having only 5 slots and one for potions. I could be ok with just 8 of them. Be i miss having all my skills that i've earned from leveling on my UI. The dev's claim it was confusing for many players that way. And some say it makes you have to think what to slot to use for an encounter. I find that a sorry claim. You still have to do this with a full use UI. I'M not an expert but i heard it was made like this because a console player's controller can't handle a full use UI. If true why not have separate UI for PC and Console. Heck they wont be playing on the same server anyways from what i hear.
