I LOOOOVE making hella orbs for my teammates. Now supers for everyone, including myself. In the abyss, a defender titan with Saint-14 is a good way too make sure everyone makes or through to the end. Use a good machine gun, pop a heavy ammo synth. Mow them down so your teammates get them orbs and their supers right away. Throw a spike grenade at the lamp in front of you as you're reaching it to clear out the thrall immediately behind you and give your team a break while they reload their guns and get their darkness gone. Pop a Ward of Dawn, and melee melee melee for even more orbs. I've also been told suppressor grenades keep ogres from shooting their ey blast. Never tried this myself as i run spike, but sounds plausible (I'm pretty sure eye blast is a 'power' that you should be able to suppress). TL;DR: Defender titan is the best support class, hands-down.
