Well system assisted actions like AA is far easier to manage for developers then wild wild west button pressing.

You don't have to go balancing hunting every skill formula if you know off hand that AA is the tiller on a boat. If I know you can get 500TP in 5 swings so to say, and your over balanced 1K WS is way too unfair, I would say just mathematically reduce damage a little and raise TP cost to 1.2k.

On the old system, you would have to check on tweak stamina, damage versus light attacks, heavy attacks, TP gauge, damage gauage, animation, etc, etc, etc.

I mean how would a developer handle the BEAST glad cadence super buff attack in current system and AA system. all AA system has to do is tweak some numbers. In current system, you have to consider 20x more situations where a player runs rampant.

AA is more elegant in the long run, unless you have an already balanced out system. We didn't. Fighting the 8 headed monster is not productive if you're getting the same results.
