People will probably disagree with me on this but I would rather have voidwalkers. I have found that 9 out of 10 sunsingers I play with are too reliant on the self revive perk which in vog was fine. However, in crotas end it's a bitch. I can't tell you how many times I've had to wipe because someone is careless and dies causing an oversoul at just the wrong moment and screwing us over. Plus a skilled player will get far more use out of the voidwalkers damage capabilities than having a super that they only use when they die. The sunsinger is outdone damage wise by voidwalker and its only redeeming quality is useless for crota.
