Your not playing on a pvp server are you? if so that will be some big issues down the road with alt tabbing.

The problem you will have with alt tabbing to tank and heal on an instance is some times the healer will have to spam heals to keep the tank up. Either because too many where pulled, you got an add that you didn't notice, or your fighting a boss fight where the mob just hits too hard. Im not saying this can not be done, in EQ when i 3 boxed, I did it with no special hardware or software, but that was easy 2 on 1 boss fights that only had a tank and spank strat. Further you get in the game, even lower level instances are not tank and spank.

If you still want to use no hardware or software to help you box, it can be done, just like it can be done without using macros, but then again, I "can" walk to work, its just a lot faster in a car.
