It's not only a Triss mess.
There is the lack of consequences from TW2, the lack of internal consequences (Brothers in Arm is...useless, for example) and the rushed third act.
The "Triss issue", at this point, is secondary.
Good point but i have to say the Triss issue fits right into all of the issues you listed. In my book they are all primary concerns that need to be address.
I don't know about others but I tried playing the game again but could not bring myself to do it. It seem so incomplete unlike the previous games.
