Hey dude dont worry. I main a Warlock and i agree with you. I always use my super proactively because of the Orbs it generates and the DPS with Heart of Praxic Fire is crazy. However, if im going into strikes with a bunch of randos and they seem to be total Nubcakes ill usually switch over to Fireborn just in case. Otherwise the damage reduction is HUGE for keeping your teammates alive and even reviving them if a bunch of enemies are near their ghost when im trying to revive them. I really think alot of warlocks need to think about why they are hoarding their supers and try to be more proactive because in the overall scheme of things you are hurting your teammates by not generating orbs. Just a couple hours ago i was doing the Omnigul strike with a random and one of my friends (Both of them were spec'd as defender titans). We were able to communicate well enough that when we got to omnigul we were able to sit on the bridge and have our supers going the entire fight. I was chucking grenades at omnigul and killing thralls when it was on cooldown to generate orbs. It was fantastic, we took her down in 1-2 min flat.
