To be honest I'm pretty optimistic regarding the changes in DAI, as I think a lot of changes that have been implemented are for the better.
Like:
-The 'middle road' approach they took for companion armor, being able to equip and vary their appearance while they still retain their own unique flair. How it turns out and just how deep remains to be seen, but from what I've seen I'm pretty cool with it.
-I actually don't mind the gated romances, as it gives each companion a natural feel as to their preferences. I never liked the 'one size fits all' approach (a.k.a playersexuality) to begin with.
-Dagger variations (slicing and stabbing). Although I do wonder what comes if you equip one of each, unless of course daggers come in pairs and not individual equips. Either way, at least now that allows me to feel okay with having two DW rogue PCs since I can develop their 'style' differently.
-Rogues seem to get more abilities that allow them to behave like rogues and not just lightly armored warriors. Caltrops, traps, I like it.
-Weapon/armor gated classes. I don't mind it at all, as it makes each class unique. Its Dragon Age, not Skyrim.
-Crafting. I never crafted in previous DA series, save for maybe equipping weapon and armor runes. Why craft what I can buy? This game though I'm VERY inclined to craft weapons and armor, maybe even potions.
-Playable races. Nice not to have to play as a human again, though I'm sure a good chunk of my PCs will be anyway
-Character creator. Say what you will about lack of hairstyles, I think they outdid themselves with the makeup and what finally appears to be a good eye color (using a wheel was the best idea because now you can actually SEE the color, unlike so many other games).
-Combat looks amazing. That's all I need to say about that. I like action based gameplay and would rather not spend forever having to micromanage every single move, but its also nice that each battle requires SOME thought.
-Dwarf female beards. Seems they took the Tolkien/WoW route with that one. But I like it because it gives them a distinctive 'hallmark' unique to them (as elves of either gender do not grow facial hair, qunari have horns, etc...)
-Qunari horns. Something may be said about the hair, but the horn styles are pretty neat looking.
Interested, but neither positive or negative about:
-No healing. A part of me is like "!!!" given that I ALWAYS kept a designated healer in my party whenever I could. However, the healing mists and focus on tactics such as guard/barrier actually intrigue me, so I'm not writing off the idea just yet. I want to see how it actually works before I judge harshly/leniently.
Concern:
-While I know there are 'general' elements of the game that go regardless of your gender/race/class, I do hope there is a healthy amount of reactivity and not just slight dialogue changes here and there. Doesn't have to be all the time with every dialogue, but it'd be nice to see your Inquisitor isn't always a special snowflake and just as prone to the ups and downs of race relations in Thedas (which aren't fantastically/politically correct).
-Dancing with Empress Celene. I do hope you're not forced into that (like you were forced to 'date' Morinth in ME2). If its optional, cool.
Dislike:
-Overlapping trenchcoat armor (though I think that's just what we've seen so far). I really do hope there are some plate for warriors, robes for mages, etc...
-No armor dyes. Kind of disappointed that never panned out.
-6:3 male-female companion ratio. Yeah, it bugs me. Those who want to run an all-male party have plenty of variability while those who wish for an all-female party have but one setup. Varric could have made an excellent additional advisor, with his slot going to another female character.
-No non-human females for male romance (seriously?! Origins didn't have it, DA2 had it but you're relegated to human). I don't mind Sera being f/f only, given its her character, but another available option wouldn't have hurt.
-Skewed romance options in general. I would have included another bi female (elf/qunari/dwarf) for an additional non-human m/f and f/f option while either making Solas or Blackwall available to both genders for an additional m/m. Would have been nice for three options per orientation as opposed to two for some and four/five for others.
-Qunari female hairstyle limitations. Wouldn't hurt for at least one long hair option.
Despite my 'dislikes' (actually, nitpicks. Some which I'll get over (hairstyles, armor dyes) and most likely forget about. Others which I hope writers/devs take into consideration for future games (LIs/party members).) I'm extremely excited for DAI. November 18 can't come soon enough, believe me.
