Well, I don't mind having to target people first, but mouseovers make things a LOT simpler.. I just point at the unit frame, and wham, spell cast. I use mouseovers for healing on my 70 shammy healer (raid, resto specced) and it works quite fine with addons like grid.

Anyhow, I made a targetting macro for each of my three toons, and I'm using that for specifying who to heal when things are getting rough.. It's just a little difficult to get it into my fingers
I don't think that you quite get what I'm saying. Yes, mouseovers are great if you're actually playing a healer character. If you're tank is the main screen, you don't want to be using mouseovers to heal when a mob breaks aggro and runs toward your squishies, when you should have been rotating sunder armor or whatever. As a tank, you should have your full attention on mobs. Ultimately it is your decision, but as a whole Multiboxers are slower to react in instances, and this could potentially make it harder to regain aggro if you miss a runner.
