For the long term I would say throw in a Shaman as that will help you on some mobs. Without a tank you are limited though. Personally, I agree with bard over shaman. I always thought a fun combo would be 5 rangers and a bard. You jut run with selos and bow kite from 5 rangers.
Remember, when the mob is moving, bow's do reduced damage, with 5 rangers though, I guess things would die fast any ways
Was mostly for the lol factor. See five rangers and a bard zipping around plane of storms bow kiting things down.
Truebox means you CAN box, but you can not run multiple accounts from the same computer, you need a separate computer per account.
