Mage Best Pets per slot

[Ploid]

1) Arc Sentinel (Stacking Damage + Stacking Spoed + Haste)

2) Hero Garlic HB (Crit + Stacking Damage + Haste) with Hero Tad AA (Damage + Crit + Haste)

3) Number 2 works for this as well. You can change out your AA for something else if someone else in your party is using Hero Tad

Note: I think it mainly depends on your load-out, with Kraken Gun for example, you won't care for haste as much. So Arc Were AA would be better in that case.
