I read your post but i use voidwalker in pvp personally. Sunsinger is a last resort in nightfalls, useful in hard mode raids. Other than that voidwalker is way more fun to use. The titans bubble shield can be a "crutch" as well as the hunters invisibility. The people that soloed crotas end did so by going invis through key parts of the raid. I drop titan shield sometimes when im close to dying. I own all 3 classes at 30+ so they all have advantages and "crutches"
