Doing damage without Missile Attacks doesn’t counter as countering something that blocks Missile Attacks, the point of Missile Hole being unbalanced is against Missile Attacks, which almost all the archer’s class tree is based on.
Broadhead Arrow and Poison = status ailment. Works, viable if Missile Hole is nerfed to 30s duration or less.
Melee Physical Attack = unrelated.
CC = Still does not counter. Being CC’ed and Missile Hole immunity are different things. Again, viable if Missile Hole duration is nerfed to 30s duration or less.
Magic Damage = No archer have magic damage, unrelated.
None of the said things effectively counters the effect of Missile Hole.
Again, please refer to the threads linked on the first post for proper discussions and detailed info, thanks.
