Rebirth Tim took it to the limit with the batfamily, Doomsday and Jor-el.
Personally I have little problem with BatGod especially on the JL. If it was realistic Bats shouldn't be on that team. But no ones here for realism.
I find Batgod quite entertaining though most times I don't take it seriously. I'm used to Bats and robin going toe to toe with heavies they have no business stepping to.
So long as the plan and tactic doesn't involve too much PIS I'm cool with BatGod.
