Yes, but there is the problem of needing a super to destroy it. There are also the only classes that can suppress other people's supers in the void. Getting close or in grenade range would be illogical and would end up with you getting suppressed and/or bombed. Golden Gun wouldn't be as efficient with the range that you would need to shoot it from because (as far as I know, I could be wrong) Golden Gun has a damage drop off that at a certain point cannot kill a shielded guardian in one shot. With this weakened power you would not be able to pop the bubbles and would have to rely on long range engagements to kill us
