I prefer being able to Rez people at my own discretion with the current system. If they are really bad and repeatedly dying I have the option not to Rez them. I've had cohealers die so much I refused to Rez them and just solo healed the rest of a duty. It's an option we can use in the current system. I've also rezzed 10 or more people in a run to get a hard fought clear. I would rather be able to force a victory on my team than repeat a duty over and over until we all have a near perfect performance. It's not pretty but it's fun and fun is something desperately missing from the healer role as it stands. I do think healers should get a Role Skill like you mentioned in addition to the Rez tool we already have. Maybe something we get around level 58 with a 180 second cool down to instantly revive someone without weakness. This way we could use it on our first death in a duty and feel less burdened to save swiftcast but still have to rely on standard Rez in especially chaotic parties. We could even do a Rez right after being revived ourselves without killing our MP. I feel like that would be a good middle ground.
