Given the humungous list I could make here.....I will list the good points instead.
It has nice graphics. . . not including the broken animation for non-human characters.
But since people will probably be asking, what the heck, here goes.
Broken Animation for non human characters.
Qnari looking almost handsome and rugged instead of menacing.
Bad hair
Action heavy combat
Horrible controls/interface
Bad AI
Lack of Tactics
Lack of auto-attack. Including no longer automatically chasing enemies that get out of range.
Ill conceived bonuses from gear. (Do we need a speical item that makes a warrior ability stronger, just that one ability?)
Uninteresting spells/abilities and too fe of them. The latter they try to hide by adding upgrades to absorb extra ability points without having to have any real abilities to put them in.
Too much randomized gear, especially the magical items.
Level locked gear
Class locked gear.
Lack of ability to distribute attribute points.
Horrible crafting, namely too much grinding for materials. Not to mention it seems to be designed to compensate for the above. Even if you craft armor or weapons using a special materials that allow other classes to use it, it won't work because the bonuses will be wrong. For example, the bonuses for heavy armor are for warriors only, and you cannot craft heavy armor with mage bonuses even if they can wear it.
Lack of healing.
Guard / Barrier. Basically useless, instead of spam healing you spam barrier or guard instead, which has no discernable difference. Heck some gear even has generate guard on hit, comibined with other bonus the guard is then unbreakable so you never lose health at all.
Horrible designs for armor. Really, all mages have robes or trench coats with very little difference except the higher tier armor has an extra belt or shoulder pads.
A very boring and ill concieved villain, this also extends to the plot. All the build up of DA2 is basically swept aside unceremoniously by choosing one side and see the other one get taken over and destroyed by the villain. Really, after all the tension they went through, the entire prequel building up the mistrust and fear of mages and the paranoia of the templar, it ends like that? It really is insulting.
Fetch quests galore, as well as meanlingless collectibles.
Large open worlds similar to what one sees in an MMO where everything is static. Some bandits can chase you into your camp and your "soldiers" will stand and watch them attack you. Heck even in SWTOR you can count on the guards shooting them down, and that is an MMO, and they are famous for not having dynamic worlds that respond to player actions.
Story areas which are suprisingly simialr to the instances where class quests take place in SWTOR.
In fact the last three combined make me suspect that this game is simply an MMO that was cancelled and repurposed to recoup their losses.
Well that's my list of bad things, and I am certain I could come up with more.
