How "twitchy" is this game?

[Snowdove]

Ive always found healing to be fairly non twitchy,

That's good. So far no one's died. lol

I use a target of target macro to keep my main target the tank and cast aero/stone on whatever they're targeting
I think its

/macroicon "Stone"
/ac "Stone" <tt>
/ac "Stone" <t>

Oh, that's a good macro. I'll have to use that!
