Alright fine. You have a point. However, you cannot consistently deal damage with your minions to off-screen enemies, because most of the time they will come back to you instead of attacking them. Whips should make your minions attack these enemies consistently, by disregarding their distance to you, and instead focusing their attacks on the enemy you tagged, than other enemies that are closer to you. Plus, the sentry summons don't have the best DPS, and you're relying on a gimmick to deal damage rather than an actual feature.
