Can you elaborate on this? Curious as I currently use zero UI/Add-ons/whatever is available in FFXIV. I'd be interested to learn more.
Also I do hope they combine actions that have similar but slightly different functions. EQ2 suffered from this and long term it is a detriment to the game and most players. Like when you have 2 actions, that that does X+100 dmg and one that does X dmg but adds 10 sec 5% dmg buff. The perfect player ends up keeping the buff up but otherwise using the X+100 one. This is stupid in my opinion and not what "player skill" should be about. As mentioned above too if you have to spend the fight actually doing fight mechanics keeping that perfect rotation up is even harder. Also you end up with 10 action bars all full of crap. It's just stupid.
I know MMOs are not a MOBA, but I love DOTA 2. Each hero, baring some exceptions, has 4-5 skills. In theory items could add another 6 if you bought all clickable things. But the skill comes in for know when to use them, managing cooldowns, combining them properly, and coordinating with others. Granted MOBAs will always have an advantage as they are PvP but more buttons to press is NOT better in the long run. Least in my opinion....
