Thanks to you too Xig, you're one of the more helpful and knowledgeable people I've seen post, so one of the few that could make me think something other than "Hate is god, everything after this is meaningless"
Sounded like most of the concerns you raise are still covered by the pally, unless his proc cure don't cover all bases? I also know from the little I did in PoD the pally cure doesn't help if your target is dead and you have to move the whole group to find something else to whack before they wipe. My biggest worries were underhealing and not enough DPS later in the game, but sounds like subbing the sham for one of the pet classes is a good place to start for my playstyle. If I have mostly melee/pet dps it'll be pretty easy to just get everyone in range, use warrior to turn mob and then switch to sham for healing and occasionally DoT with nec. If it turns out my fears weren't unfounded, switching 1 class out later for a cleric or 2nd pally sounds like it'd be alot easier than trying to swap 3 out now.
