I loved DAO and spent close to 90 hours on it, but lets be real now:
Fade was awful
Orz was cool
Politics in orz was BORING (noble dwarf start or whatever is so BORING AND UNINTERESTING)
and the beginning of the game just really stunk
lets not forget bioware has NO fucking idea what balance means in their harder difficulties. I don't even think they try it themselves. Examples:
In ME3/ME2:
Insanity and hard is literally just damage+ and health+ to the enemies, and you deal less damage. That's not hard, with their designs in place, it ends up being really plodding and tedious and oops you popped your head out for 1.75 seconds too long, time to hug that cover and pop a medpack with veins all over your screen making it hard to see that guy flank you. Oh time to restart. That's just frustrating.
In SWTOR (or as everyone in Starfleet Dental used to say "sweater"):
EVERYTHING. The entire thing was based upon having a companion to the point where if you didn't have your companion out, or someone with you, it was long, slow, and you'll probably die because you don't do enough damage, especially if you're a squishy class. Oh, and your "tank" character dies like a bitch very easily too unless you hold the game's hand. Don't even get me started on the raids. I will rant for fucking pages.
in DA2:
Take ME3 Insanity mode for nightmare, then put in friendly fire. Now those spells you're using to try and plink away at the absurd healthbars of normal and elite enemies, well, they kind of one shot things. Things here being your own squadmates. Your squadmates, who by the way are colossal retards, even when you do custom tactics, they still like using spells they shouldn't be using, or activating sustained abilities they simply shouldn't ever use in 99% of situations. Or they'll be like "i'm attacking that guy there! oh sorry i ran into Temptest and died because you looked away for half a second even though you're pausing every 1-2 seconds in combat, lolz" Couple that with no cancel ability and instant teleported in new waves of enemies, inability to use threat drops/cancels due to animation locks, or any move for that matter, and you're not going to have a fun time. Oh did I mention improper aggro threat usage? There's no table, it's whoever is doing the most damage in a 10m area nearest me, dragging trash mobs near the tank and threat dropping while the tank aoe taunts (no directed non-gc taunt) and it's like im playing goddamn vanilla wow all over again.
