Probably slug shotgun (chaperone) with nf or Luna OEM suppressor grenades with the artifact mod and bubble with weapons of light. Combine this with two good roaming supers and you’ve got yourself a pretty good comp team. If not you can always go with erintil and a pulse/thorn or last word sniper. Use synthespts bottom tree striker with the thunder coil so you can one hit punch after getting any kill. Honestly titans are pretty strong so you can use almost anything but OEM is the best exotic in the game, there’s a reason that’s the only exotic titans ever use in comp.
