Well, how come we don't have a scan and flying healer?
That is not serious. And if you think it should be, get out.
Anyway, apparently support is helping get loot as well as heals. I first didn't understand why Loba got the plus sign, but I suppose it makes sense with the loot help. It's going to be hard to beat Lifeline in heals, the way she is designed, but someone can do a sort of mid-level heal...maybe instead of a drone thing, a one shot instant apply medi-pack. Like a stim injection heal.
That's another idea by the way, a sort of give another person a stim, treading on Octane but I could live to see less Octane. It would need a much longer cooldown and/or a no repeat until fully regenerated on that character, or something else but it's an idea.
Here's an idea for a support character: Someone who puts down an anti-aircraft turret. It shoots down only people who are two levels or more above you but does massive damage. Yeah, do that. Or another one where if you scan the support character, you take half your health in damage because your eyes bleed out. I'm sure we can come up with a sci-fi excuse for anything, so lets do it.
