Sep 21st 2009 5:27PM With my playstyle, I find a mix of both is good.
Spell power is good in that your heals land bigger and can cover larger gaps in hit points per cast.
Intellect has a three-fold benefit. It increases your mana pool, increases your mana regen (replenishment), and increases your crit.
Crit is very beneficial for both disc and holy.
Generally speaking, if you feel your heals are too small, gem for spell power. If you feel you need more mana gem for intellect (not spirit or mp5)
Jun 1st 2009 1:37PM I agree with everything you have brought up as far as social interaction is concerned. However, I feel the original inquiry is more about the design of the game, and how it influences our goals.
The landscape of the game has changed drastically. Blizzard has shifted views from progression and epicness to achievements, loot, and increasing/maintaing player base. They want everyone to experience endgame content, have something to do (daily), and make good loot easily attainable. These changes can kill comradery and a raiding guild.
