So I'm in the process in moving from being a faceroller to actuarry know wtf is going on in the game, be more able to push the right buttons at the right time and maybe some time in the future be ready for heroic raiding. Currently at ilvl550, haste build, seems to work ok.
Newest discovery is that the whole stat weight system mrrobot and all similar systems are based on, doesn't work, since how much benefit each stat gives changes according to how high the other stats are, and also to some extent spell usage, thus making it encounter and playstyle specific.
But most importantly here: I can't seem to make any calculations that concludes going for the red socket bonuses worthwhile. By manipulating stat weights in mrrobot and see how a non-intellect gem build would turn out for me:
Raidbuffed spellpower with intellect gemming: 41.5k
Raidbuffed spellpower with no intellect gems or slot bonuses: 39k
This is a 6% reduction. 1% crit also goes away, which means loss of healing from the missing intellect will be 7%.
The gain, however, is 8% mastery. Thus it is a good trade that can give me a slight boost to non-HoT healing and a significant boost to HoT-healing.
Prove me wrong!
