To be honest i cant speak about SWTOR and Rift as i dont play them/belong to the community.
All i can tell you is that Blizzard are big into policing these types of things, some where in their terms of use is their one physical click=one in game move (comes under boting) thing and i have heard of people being baned for violating it.
I think its because their view is it will give players that own said hardware/software an unfair advantage
over people that dont have/can afford said hardware/software.
So long story short as long as you keep it to the one physical click=one in game move rule you should be fine regardless of what software you are using. (from what i hear Blizzard runs software on your computer while you play WoW to make sure your not doing anything naughty)
