I dislike that idea. If there was a team of sentinels, they could all hof and it would be quite hard to even grab the flag. Same thing if there was a team of snipers. I like the idea that teams can be comprised of anything they want. Having a team of all hofs means you are sacrificing offense. A team of multiple healers means you are sacrificing damage. You cannot deal damage while healing. So if you are in a 3v3 fight, and 2 enemies are using their heal guns, just target them as they cant attack you back without switching weapons and stopping their heal. And I proposed no self-healing so it can't replace the regen core and health regeneration. Also, its only meant to be MINOR heals, like if someone shot rockets at the person your healing constantly, he should still die fairly quickly. You are just prolonging his fate. So, the fact that you are making yourself very vulnerable in a fight when healing more than makes up for it possibly becoming op as long as the heals remain minor. Plus, if everyone on your team is healing each other, you cant deal any damage back to the people shooting at you. Again, just prolonging your fate.
