For DPS...Cyborg (damage) and Nubia + BWL (passives) Sound about right? Unless you're a pet build I guess?
Kinda depends on the power itself, for a few. With Rage, you really want cyborg passive since you drink through your power bar rapidly. Pet builds, Aquaman likely a must. Pugs might need calc bot for that extra healing, or active Nubia. The giggling Batman is very helpful though too, with the random cards.
Would be for my main alt which is munitions, I do enjoy Cyborg's passive power regen. Using House bot and Nubia + Cyborg right now.
For Combat: Cyborg (AoE) or HoL Bot (single target) For Passives: Cyborg (Power Regen), Emperor Aquaman (for the Combat Ally cooldown), Flashpoint Batman (defense buff), Queen Diana (Passives are situational) Nubia's passive group buff is nice but can turn into a wasted slot if someone else is using it. Batman Who Laughs has arguably one of the best Passives for all roles and a debuff passive for trolls.
The "save your cash" meta: HoL Bot + Cyborg & Calculator Every single end game player should have this combo at max if they aren't going for Legendaries.
The “least I could do” for alts: 2000 ally favor into Oracle- bot and 2 rare alliance to rank up and unlock the passive ability and then parked there. I let them die liberally now that I’ll never pay to repair them.
