I think the g402 or 302 would be great for you, if you like finger claw type grip.
Deathadder is still one of the best ergo right handed mouse there is. If you require more buttons (esp for sc2), then you'd wanna think about getting of those lazer mmo mice offered by logitec and razer (I'd go with the logitec one).
For example, when I used to play tos on SC2, I'd have your normal control groups 1-4 bound on the keyboard, but separate production plants will be bound on extra mouse buttons under my thumb. Then I'd have groups of probe or special unit bound to other buttons on the mouse so I'm always macro'ing. Was very useful.
Still, for dota 2, I don't think any can match CM storm spawn/lower dpi equivalent or the g302.
