*I only have two weapon choices per class, and no weapon choices if I'm a mage. DAO allowed you to use all ten weapon types on each character. DA2 restricted you to seven for Warriors, two for rogues, and none for mages.
True.
*I have no control over my own attribute gains - only what the developers allow me through the talent trees (which are all apparently primary stats only) and the supposedly optional crafting system.
It's optional so that those who don't wish to bother minmaxing their character can just pick up whatever drops and keep whamming. For those who do want fine control over their character's attributes, crafting allows even finer control than Origins did.
*I am limited to eight abilities while in combat, and cannot alter them without exiting combat/reloading. If I have to explain why this kills versatility builds by itself, well..
It kills one-man-army builds. It encourages total army builds. Rather than have everything available on one character, you now have to combo between the members of your party to get the optimal results. It's a different kind of versatility, but it's still versatility. And a more challenging variety to boot.
*I cannot change weapons during combat. Even DA2 allowed this to some degree.
*I can't have two weapon slots, which DA2 did not allow. In DAO, I could be geared with a range weapon if I had to engage at range, or a melee weapon if my ranged character was engaged in close combat. In a game that is supposedly all about tactics, I should not have to explain why the lack of this, combined with the unchangeable slot limit is a bad thing.
It isn't. If anything it increases the tactical management. Instead of simply plinking at an enemy at range and switching to melee when he closes in and vice versa, you now have to constantly mind the positioning of your characters. Where are the enemies? Where can I move to avoid the one closing in on my archer? Can I move there without coming into range of another melee enemy? Where are my melee characters? How do I get them to hold of the melee enemies? Can I position them in a choke point? Can I do so while avoiding them being surrounded and losing their defence bonus?
Yes, one character can no longer fight of every single opponent in the game. Yes, you now have to use your party more efficiently. Both of these amplify to the tactical depth of the game, rather than subtract from it.
