Leveling Up Alts Post-60

[Dvl]

Couldn't you do the same/better with 5 casters as long as one is a Warlock pulling with 'Eye of Kilrogg?

You would need a shield for the Eye anyway so one of the casters will need to be a priest. It's also difficult to group the mobs when you don't have a tank and have limited mana on your casters.

does healing the group out of party effect xp also? Is the priest supposed to build up threat via healing himself, then leave group and AOE on levelers or?

You can heal as much as you want from inside (while the pulls is going on) or outside the party (while mobs are being killed). Healing outside the party is quite difficult but doable for a multiboxer I guess. In Deadmines our priest actually tanked the pulls with elites so he would pull and gather the mobs, then grenade for initial threat followed by the mages spamming arcane explosion. Blizzard slow is not available at this low level. From Stockades onwards our priest only pulls and gathers the mobs and they are then kited with blizzards.

As long as you can get the kills done before the Priest teleports out (or at least get the mobs down to a manageable level before then) I could certainly see value for having an un-killable tank. Even more value if that un-killable tank can heal the party effectively while out of the party...

A multiboxer may be able to establish healing macros for each party member such that when you click raid frames on a member of the party it sends the right healing commands to the Priest (even with the Priest out of party). Would take some planning/effort in advance but seems doable off hand...

I thought doing any damage on the level 60 would significantly make the xp a lot less? Does it depend on the amount of damage or something? I am definitely gonna play around with this because I plan on making some lvl 35 alts haha.

Yes, any damage from a high level will reduce your xp but it's important to understand when you can afford to take that hit and still level fast. At low levels before you can even get improved blizzard it's definitely worth it just so that you can aoe in instances at all.
