I've been lurking around these forums for a long time, and have been playing Holy Paladin since vanilla, when i did the same as I do now: spamming Holy Light :P
On Galakras: Healers should watch the adds that charge the NPC's, you can stun those with hammer of justice / fist of justice.
On Iron Juggernaut: You can use Blessing of Protection to detonate any mines.
