That's what you're supposed to do is pick the right gear and perks... I main a Titan and warlock basically. Like I said it lasts forever I don't run defender so can't suppress it and don't run void walker 100% of the time so I can't res on it. I challenge storm callers with my doctrine and win about 50% of the time however I got killed by one yesterday he killed 3 teammates and killed me again 5 seconds after I spawned. That's way too long.
