The stats listed by the OP are all higher than mine, at 35. Regardless of exact priorities, at 35, I'm able to solo fine with unbuffed Agi of 180, Dex and Sta of 148 and Str of 139 -- I use potions made by my shaman alt to buff all 4 stats (plus levitation, SoW, skinspikes and regeneration potions) when I really need them in combat. And of course the drakkin dragon breath DoT helps. I like to group, but I won't let a group try to make me the tank -- that would be crazy for me. The monk is my 6th alt, so I am not committing a lot of effort here until my other alts are set. I also expect the 4 stats will all be about maxed by 50th or 60th level.
