Just to try and understand u.
'Old' version is the Community Edition or the version prior to the new Interface?
If the latter, it doesn't make sense. Only the interface changed, the code behind it remained unchanged. Plus you're comparing a resto routine from before WoD & after WoD - with all the healing changes that went on during the expansion, that's not a fair comparison.
Now if u could define 'much better' , 'shit' I might turn ur message into something useful.
I tried this routines 2 weeks ago and I was TOP HEALER without mana problem, no I have much better ilvl and Im the weakest healer with huge mana problems. Mby I should restart HB or sth? I dont know
