Zerk will outdamage voker aginst mobs anyday. And rangers can tank up to 50 with ease, toss in herb and they are good without resting. So why not let the ranger tank and use two zerks for damage? Way faster. Thats for ranking though. For gear/deso its a different story, I would go healer/cleric for the tank, and two zerks for damage. I'd also go with more than three people.

Its easy to kiss Raargant's ***
Over six years playing here off and on.
Healers are nice for the additional defense and food/water they bring along removing the need to sleep. Bmages are nice for haste.
Or slowing the healer.
Re: Senthar -
Most of us have been playing for a lot longer than they should have. It's just that the addiction holds and won't let us go. And I like my addiction, thank you. Cheaper than crack, too.
I asked a chat buddy if he knew of any good game d/l's and he introduced FL to me using the phrase "I know of something, do you want to ruin your life?"
And voila here I am a year down the line... And, yes I am mildly addicted... I can stop when I like..... honest...
