Archers need their damage classified fully as either a melee or magic type and you play a mini solo, you can pretty much run the solo game if you play correctly and have a lil rr.
So in all reality all it really affects is archer groups, since their "magic" arrows destroy melee ablatives. Which means archer groups will drop you a little faster. Half my targets when i'm solo don't have ablatives up anyways, because i play in area's that have lower action and less targets, since they see less people they dont pop all their stuff religiously knowing there is something there to fight. It's not until i go onto ev or in ruined keeps that stacking really makes a difference.
But also remember we're talking about melee ablatives only, you still have access to som wh and smaller ablatives, 500pt ablatives are what need removed, it's not hte 200pt ablatives we bitch about.
