I specifically take Adepts, precisely for a decisive strike against archers. Although, I don't know how pro players do it here.
I also take Adepts; they are overpowered:
They have +4 attack, and with equal hero stats for attack and defense, this is a +20% damage multiplier.
+They cast Bloodlust at the expert level, which gives +12 attack, resulting in a +60% damage bonus to the selected unit.

And on top of all that, they have the passive skill Purification. It's always nice to remove buffs from the enemy.
Incas are less effective, even considering they have a much larger set of buffs.
