Just the archers del this DMG i guess. i hope 
rogues got feint fot cc the mob, and scout got flu flu. This 2 skills can prevent that ? 
you think so? When you get ambushed they WILL land at least 1 attack each. 1 attack is more than enough. Tho i’ve heard that they have balanced monster’s a bit.
I see. Anyway, I think You didint got my point: Scout invi => Feint => fluflu just to be safe => burst the mob down. The mob will not attack you since it can not see you.
How is that different from burrowing and killing them anyway?
For that combo above you just need scout and rogue c1. you have 4 free ranks of archer to choose. 
I think that rogue and scout are the 2 best archers ranks that suport a very fun and efective way to play any archer.
Even with a 100% dps pve mindset, This 2 classes / ranks can do a lot for any archer: sneak, feint, fluflu, Cloaking, flare shot, (this last one, ppl forget that it lasts in the ground for 15s).
