I'm gonna be another player who says "The hair" needs improvement, but I liked DA:I character creation best among all 3 series. Though, there was once, part of my characters eyeballs were peeking out over their closed eyelids and it freaked the hell out of me.I thought I positioned the eyes too far back into his head but no matter how I tried to position the eyes, they still jutted of as he blinked....so maybe try to fix the small, weird details from happening?
The romance is amazing but I'm a greedy player and I need more love in my life. There should be more bi characters so we don't get so disappointed in being unable to romance characters like Cullen, Sera or Cassandra if we were the same gender as them. And please, let us romance a dwarf too! There are humans, elves, now even a Qunari but no dwarfs? That's just sad, especially since I really liked Scout Harding. I would also prefer more character quests than collecting stuff that I don't see the need to collect.....like the bottles of thedas.
I thing that I absolutely hated in DA:I was the limited slots for skills!!!! DAO and DA2 had a dozen slots but we only get 8 slots for DAI. Its frustrating! And also, please gives more AOE skills back. DAO and DA2 had awesome AOE skills which DAI doesn't really have, unless you're a rift mage. And another important skill....HEAL! there's no heal in the game unless you're knight enchanter?! Which requires focus to cast?! Also, to be honest, the rogue specialization kinda sucks. At one point, I kinda regretted playing as a rogue, except for the fact that a rogue can open doors which other classes can't.
The mounts were nice (at least most of them are) so I hope you keep that. But maybe allow the other team members to ride mounts too, instead of disappearing. I miss a lot of party banter because I'm mostly on the mount. Even when I'm not on the mount, the banters are so rare, unlike in DA2 where there was a constant stream of party banter.
Also, please add back the option to choose or world state if we don't import save files. DA2 had that option but in DAI it was only default world state. For the next DA game, it would be awesome to play as a Tevinter slave or an Antivan Crow. It would be more surprising to have these kind of ppl as a hero. Instead of looking down at a particular race, they are looked down upon because of their status or something like that. Maybe throw in darker scenes like showing us the actual torture they are put through like whipping? That will make us feel more sympathy for them instead of always just hearing them say that their tortured, you should actually show us that they're tortured.
Random spawning of characters like the chantry sister in hissing wastes was just tiresome. I lost count the amount of times I had to run around the hissing wastes just looking for one woman. If you do intend to try something like that perhaps on a smaller map? Like the quizquisition guy.
Better armor would be nice too. I liked the way some of the outfits made them look regal, like the high keeper robes or the warden armor, but some others just looked weird on them, so even if they had higher stats, I couldn't bear looking at them for the next 30 hours or so into the game and just sold it.
I liked how Varric was a playable character for 2 DA games,and how you brought back characters from the previous DA games like Hawke, Leliana, Morrigan, Alistair..... so I can only hope you bring back more, like Fenris (Tevinter), Zevran (Antiva), Sebastian (Starkhaven), Isabella (Rivain)...after all, we'll be exploring Northern Thedas, right? Oh, and don't forget Dorian!
I get that Solas would be the villain in the next series but he didn't seem all that badass to me. I think you need meaner villains. Corypheus was kinda too easy to beat at every turn. Funny how a guy with a dragon and a army of mages/ templars isn't doing much damage. If he wanted to cause havoc, you'd think he would just fly into Orlais or Ferelden on his dragon, blow some fire (is it even fire?) on them and burn Southern Thedas to ashes instead of giving the Inquisition the time to run around collecting bottles and mosaic pieces. So yes, I think you seriously need meaner and darker villains. DAI just wasn't dark enough. DA2 was full of it though. Mom dies, brother/sister dies, siblings betrayal, companion/ lover betrayal,....oooh, the angst is amazing. The next DA game needs more angst.
For now, that's all I can think of but I'll be sure to add more if I can think of any.
