I'm an outside to inside player, I main Jade Rabbit, then either a void SMG or side arm for close in targets, I use Astrocyte Verse, no one is ready for you to be blinking around and you can push very effectively. The blink also applies volatile and you get improved Airborne Effectiveness, you can come in from above and get guys before they even know you're there and finish with a melee if you have to. You can go from one side of the map to the other with your super--and you should.

As a Warlock, I have been playing a prismatic buddy build with Getaway and elemental honing weapons. Primary reason for going prismatic is phoenix dive and the uptime on elemental honing. Using the dive to pickup nearby crests while staying in cover and healing (so can use it mid fight when in SoF). Playing passive for me, doesnt really work on most of the maps. There are a few outliers like Vostok, where I mostly just try to hold the B section and cover the power ammo spawn. Healer with boots/lumina actually works fairly well, so long as I am not the top player on the team, then I just dont have enough aggression around me to play passive. I find that so many Warlock players play too passive, and its hard to gain any ground and grab the crests from enemies that we do kill. Scatter/Axion builds dont work so well against both Hunter and Titan because they tend to be much more mobile.

Stasis with chromatic fire being hard slept on. Half health explosions and 5ish seconds of aoe slow. Edit: Probably gonna make a post about it tbh.
