Fun thing is: Archer Thralls sucked already, even more so now that RHTS have been nerfed to pirate level and bows and arrows have had their damage reduced.
But yeah, I see your point. It doesn’t make sense.
Actually, nothing they did in this AoW makes sense. They should really stop touching things they clearly do not understand.
But hey, now we have cannibal brutes with 2.8 ranged multiplier 
Once again: madness. Madness and stupidity, Funcom !
