I'd love to be able to tint weapons. Would also be nice to have some more options available for armor/weapons. Defender, Vanguard and Battlemaster all look pretty similar and even though you can tint them now the leather option still has no effect, which is very disappointing because the leather skirt they all feature is awful and there is no way to deemphasize it.
Also some more one handed weapons might be nice. Really what I'd love to see more than anything is for someone to make some updates to the algorithm they use to determine "random" treasure drops.
It kills the RP aspect of the game that 90% of what I get for loot is either a Qunari Visor or something to upgrade Bianca, a one of a kind completely unique weapon. It's completely ridiculous. It would be nice if the random drops were at least occasionally useful, I almost never seem to get anything my character can use. If I'm running a rogue, I get a ton of crap for a warrior, if I'm running a warrior, I get daggers up the wazoo - it's rather frustrating.
Also if I have a schematic for something, then there shouldn't be any race restrictions attached. I can understand that the Orlesien army may not make armor for elves, dwarves or quinari - that makes sense. But if I'm having it custom made, it makes no sense that such a restriction still applies.
Also, tinting prior to skyhold would be great - The only halfway decent armor it seems you can get until you get to skyhold is that armor of the dragon stuff, and while it doesn't look to shabby in darker colors the all white version is hideous, so bad that at the moment the dwarf sword and shield warrior I'm playing is still wearing his original mercenary armor - with the piddly armor value of 40, because the only other armor I've found for him so far after reaching 6th level is all so awful looking I just can't stand to have him wear it.
