Followers -- what am I missing?

[MongoJerry]

If the follower gets 2.5x on a dps stat, then I'll try stacking some. The amount of base DPS even with a "good" weapon seemed so low I just have been using them as meat shield/CC.

Understand when I say "decent," I mean like 10-15% of your dps, but it's not nothing. Their cc and aura benefits are of course big benefits.
