Skye effectively counters Kinessa, as first, Kinessa doesn't have any reliable movement strategy, and she cannot self heal. Additionally, Skye can evade Kinessa's shots, unless by some bad luck, gets hit by Kinessa, which means Skye can get close.
Maeve struggles against groups of enemies, so stick close to your team, especially if you are a support, because you can pressure her either fight, where she will most likely lose, or to flee.
As Maeve, try jumping on top of your enemy to confuse them. Players do not tend to aim directly up, so the moment of delay is enough to land a few shots on them.
When an Androxus activates Reversal and you have fired to much already, dodging around makes you a much harder target to hit. Also, if you want to deal damage, and you have an AoE attack ability, aim slightly in front or to the side to hit him.
