I ran middle tree Arcstrider with Arc Battery on my Hunter and bottom tree Striker with Thunder Coil and Synthoceps on my Titan. I got so many Annihilation medals using bottom tree striker. It definitely didn’t matter what my skill level was at times. I’d just proc Frontal Assualt and punch people. If they were all in close proximity, they were done. I didn’t use my Warlock at all in comp. I might try next season.

Use top tree arc, I think that's the right one, it has damage resistance built in which stacks with arc battery

Yeah. It does pair better than middle tree, for sure. I like the deflecting super though. I’ve bounced back a few rockets using it, even a Blade Barrage once. It came in clutch a couple of times.
