Blessing was: I cast it while playing trinity for -
A) to make me invulnerable and use my Penta and Link as a massive close quarter AOE damage dealer and simply let me be lazy as I run through any mission.
B) To allow my teammates to be lazy and take no damage through whatever mission
C) To grant immunity to my teammates who need to go rez an overly aggressive player that thought they could be lazy because the trinity on their team.
D) To heal the one guy taking a bunch of damage in a mission I didn't really expect anyone to be taking much damage.
Frankly blessing needed to be changed because A and B were an issue in design, but right now I'm worried about how it works.
If i'm watching health (and usually I do) and I see someone start taking damage to their shields by the time they start taking health damage they more often than not are down by the time I cast blessing. Now that cast is good to no one if the other players had no health gone? It does them literally no good. Can I cast it again right away?
If I did get the cast off in time and saved the 1 player taking damage, then what about the rest of the team? They have no protection. What if stuff is starting to get hairy? Should I let one guy just die so I can make better use of blessing with an incoming storm?
I'm basically worried blessing was, yes essentially abused and made the game overly easy mode. But with this change? where blessing as it was, was a skill that was more needed or took effort to use correctly? It won't do much good.
Instead of damage mitigation or immunity maybe it can buff shields and health for a time and give them a continuous recharge. So say, if someone is taking damage that the damage rate would have to overcome the recharge rate to be noticeable. At higher level enemies this will get noticeable quickly but you can run, take cover and recharge?
Something to make Trin more of a healer and less of a tank is needed, but the change as it is suggested doesn't make her a very good team healer.
*Edit* I was typing when you posted this. But you said it more succinctly than I did. Though I do think reactive healing can work, you need a LOT more healing focus. Like a healing gun, or an ability to target players. Basically it becomes your ONE job to heal. I'm ok with that, but this change to blessing doesn't do it.
