Alot of PC users have modified Wardens and Hawkes you know.
Then they better be ready for people to complain, for good reasons.
*headdesk* People got mad because there characters looks where screwed over, and it is a valid complaint. Just because YOU don't think it is does not change that. If Warden and Hawke DO show up, there will be complaints. Many of which are valid.
What does that have to do with mods? Bio not handling their own imports is one thing, Bio not supporting a third party mod is quite another.
Seriously, where are you going with this? Some folks modded their PCs in the earlier games, so Bio shouldn't enable the rest of us to re-create our PCs in the new game out of fear of offending the entitled whiners?
If Bioware's game assets went wrong, then Bioware are obligated to fix them.
If third party assets not made by Bioware go wrong, then Bioware are not obligated to fix them.
If I added a mod to make Ser Gilmore a romance, I do not have the right to complain that Bioware didn't recognise this romance in DA2.
If I added a mod to make Morrigan have blonde hair and blue eyes, I do not have the right to complain that Bioware didn't make her look like that in DAI.
If I added a mod to give my PC hairstyles that didn't exist in Bioware's DAO, I do not have the right to complain that Bioware didn't import that hairstyle into DAI.
Mods will only ever affect the one game you are modding - they cannot be imported or otherwise incorporated into later games because, as far as the code is concerned, they should not have been there to begin with.
This is simply how mods work, no matter what game you are modding.
I played on PC and I use a few mods. I anticipated the possibility if the Warden and Hawke appearing in a later game, and so I created my cannon characters with Bioware's assets, so I could import/recreate them as necessary. If you didn't do that that, then that is your issue, not Bioware's.
