Aggro, Melee, and Necro pet vs Mage's

[BBIII]

I had planned to play a monk in my small group of friends. They all seem to be content playing CasterQuest, but I figured as a monk I could pull and do some tanking and have some respectable DPS. Also, low maintenance with weapons and gear.

However, For some reason I thought monks got taunt. I now know better. In a group with Cleric, Enchanter, Shaman, Necro - there wont be a root until level 8. So it seems like the necro pet and/or the shaman will be tanking for some time. Is there any hope in vanilla a monk will be able to hold aggro with raw DPS in this group? Will taunt make a real difference here? How long before tanks/hybrids can really start maintaining aggro? Lastly, Whats your pecking order for melee aggro without procs? 1. Paladin 2. SK 3. Ranger 4. Warrior?

I have been trying to tempt the necro to go mage, but he seems very unmotivated to be a mage pre-focus items. Is there a large discrepancy in necro and earth pet tanking abilities pre-focus?
