DA2 was the button-masher that couldn't even button-mash correctly. Here's "gameplay":
Mages fire off everthing and run into a corner. Melee move to block for them. Enemies disappear using magic thief invisibility power. Cross fingers they backstab, er, frontstab melee instead of oneshotting mages.
If mages oneshotted, reload.
If melee half-shotted, melee scrape away, giant swords doing tiny fraction of the damage the thieves knives do. Mages do nothing waiting for their attacks, the real ones, to recycle.
Thieves do another invis cycle. Mages not recycled yet. Cross fingers thieves attack melee not mages, reloading accordingly.
If melee take second round of magical atomic bomb thief frontstabs, they are dead or close to it. Mages cast second round of their attacks finally, cross your fingers, there won't be a third round.
