Ok I can safely say win7 is genius. I made a partition on 2 nd hdd, installed and everything worked! Transferred a toon to 5th account, and instances/shattrath are smooth. Now thought I'd share my current config

got pally spam macro on keys 2,3 and 4. Got dps spam macros on the 1,3 and 4, boomkin on 1 and 3 only. This allows 4 to be used for tranquility

Now the reason I have effectively 3 same dps keys is to allow the resto shaman to heal Tank at different intensities ie

key 2
/castsequence ,,,,,,,,,,,,,,,lesser healing wave

key 3
/cast lesser healing wave

key 4
/castrandom riptide, healing wave etc...

anyone else doing this or suggestions?
