To me both systems work, so i'm not strongly attached to either one of them. Given how much I use at least 3 of my 4 basic attacks with my main class (PGL) I do wonder how they'll transfer those over into an AA battle system. While I personally don't prefer one over the other, I will say I will probably give the nod to AA in this game since my two qualms I have with the current system are not easily being able to communicate in a fight (yes VOIP does eliminate that problem, but i'm not always on a VOIP) and actions not getting recognized.

Granted the actions not getting recognized will still probably happen even without the 10 or so extra "basic attack" keys getting hit, but it is something that is annoying when i'm engaged with a mob currently, and will most likely happen a lot less without having to hit every attack manually. Either way both system work for me, so i'm definitely willing to get AA a shot and will probably prefer it in the long run, but I still have nothing strongly against manually attacking.
