>b-b-but you can just turn the quest compass off!
It doesn't fucking matter if you can turn the UI off you dumb motherfucker the game isn't made with not having those indicators in mind.
Irrelevant comparison.
Quest compasses are 100% needed because quests descriptions have almost disappeared, most objectives are fedex, kill x or find y and most games with them don't allow any other mechanic to find or investigate targets of said quests. For example, there is NO WAY to find that one vial with poison in Skyrim without it.
This game is perfectly playable without any battle UI indicators. All moves can be seen, identified and reacted to just fine apart from some out of camera 1vsX. I'll probably be playing without any UI for single player but of course, in multiplayer, unless it's forced on everyone, it's added difficulty for no real purpose but personal preference, hence my comment on it being forced for some modes.
Shadow of Mordor game is a good example of the difference.
The quest/task indicators were mandatory because the objectives were just abstract indicators but turning all combat UI made the entire combat system pure epic because you could still perfectly react to what was happening.
Anyway, maybe you're some superduper dude with reaction times up to some weird level with superduper PC and superduper non stop perfect connection to everyone everywhere, but for most people with varied computers, connections, ages and game experience, shit is plenty fast enough. Heck, by the end I had high prestige and was mostly paired with similar prestige players (which means time, not skill, but still) and the only real limitation/difference was tiny latency issues on one side or the other, not skill or how fast moves were. Of course, because of it, fast classes were favored but it's not the point.
