Here's a set of questions -- why doesn't autoattack exist in the "regular" (non-Tactical Camera) view? And why doesn't my character automatically move toward enemies upon selecting a skill or hitting the autoattack button?
Dragon Age II handled its melee classes very well in this respect. We didn't have to worry about holding a button down, and instead our characters automatically performed their auto-attack and left us free to use their other special abilities. Quite honestly, navigating combat and getting within striking range (which is difficult to assess) before commencing autoattacking, while simultaneously trying to flank my opponent and plan my own skill usage, is pretty cumbersome.
Dragon Age II had my character automatically lock on, move toward, and continue moving toward my enemy while performing autoattacks when possible, all with a single push of a button. There was no need to hold an 'attack' button down, nor did I have to continue moving toward my opponents. I could instead check on my allies or use my cool skills strategically, and the result was a fun combat paradigm which I definitely enjoyed.
It's fine to desire a more 'tactile' sense of combat where you "feel" every swing and actively move in an action-RPG type setting, but with tons of enemies, several allies, and the complexity of managing a squishy Rogue in the midst of all this, I feel that something was lost. I would definitely appreciate more functionality resembling Dragon Age II's combat system in this respect.
Ranged builds (Archery Rogues or most Mages) in Dragon Age: Inquisition do not have this concern, since they don't have to actively keep moving to continue hitting their targets. They can simply hold down the LMB or R or whatever and rest assured that their attacks will land. Active movement to maintain DPS (and not just re-position to avoid enemies) is one less concern they have, and it makes them far more user-friendly in combat, to the detriment of Dual-Dagger Rogues and all Warriors.
At the bare minimum, I'd like for the system to let me 'click' my LMB once to start autoattacking the targeted enemy so long as it's within range, and automatically resuming autoattacks if it moves out of range and I follow it afterward. Even if I have to keep moving around actively and my character doesn't auto-chase his targets, at least I can avoid devoting mental processing power to managing the actual autoattack sequence itself, letting me savor the fun parts -- all the wonderful skills you've implemented.
