I would not mind seeing a new model Bishop turret that fires off rockets that do AoE, then have it upgrade into an Automaton King armed with a mortar. If there is need for an AoE battery builder then put in a second ability similar to Hotshot/Air Anchor that does AoE or attach a minor battery charge gain to auto crossbow. This way every hypercharge in AoE situations builds battery for more Bishop/King use. Since ST has battery gain on the main ST rotation and the hard hitting Air Anchor.
