how are they gonna fit all those icons on the screen anyway without cluttering at least half the screen? and touch movements? so much for accuracy...
accuracy?
What accuracy? There's no such thing as accuracy in WoW outside of a stat that determines if your character is accurate or not.
As for clutter, you'd be right there. Even if they vastly simplified the display, phones are tiny.
Hide/Unhide menu + hotkeys (if buttons are present), it's actually quite simple.
I was thinking more HP, rage, buffs/debuffs, target (and their buffs/dedebuffs), quests, party members, etc. The screen can get pretty cluttered, even if you can hide most things it'd be a pain.
I'm pretty sure an app like that wouldn't be meant for hardcore raids, just for some basic farming or exp'ing in easy areas. Next Target --> Attack, two buttons is all you need for that.
Besides, who has the time for a long raid on a phone? The battery would be dead before you're done. Those are reserved to the PC, the rest can be done mobile.
