I main a defender. I do know that there are a handful of things that can be annoying. Damage reduction is fine to me, I think I just dislike the fact it can be used in close quarters. Like when a sunbreaker runs in my bubble and throws hammers and kills me. That's fine that I died, but personally I'd like the splash damage of the hammers to hurt the sunbreaker who threw them too. That would make them be used more cautiously. Just the same as rockets and grenades. Use at your own risk. The sunspots potentially generated wouldn't hurt, just the main explosion.
