Okay, so, Yes I did just get pwned by this and I rage quit. Lets just get that out of the way. Regardless In serious discussion, is it really a good idea to let Supports get Juice from healing? Okay, healing Pros I can manage and agree with but healing their own or friendly Firebases gives a Support Juice?! Was just in a game on Ammo Mule where two supports with Hacked firebases camped in the centre section. Everytime you walked past the door you lost half your health, and everytime you tried to shoot at a firebase both of them healed it up and it actually gained health. They then juice rushed into the base killing and Turret destroying again and again and again from all the juice. Is this really a legitimate way to gain juice? It would be nice if someone other than a Support player posted.
I am cool with Supports gaining Juice from other players and even bots but for firebases and turrets, not so much. If not then the rate at which they earn Juice doing so be a bit slower.
I haven't committed to a single class, so I hope I qualify as not-a-Support. Getting juice from healing is definitely a little sketchy in certain situations. I saw a pair of supports healing each other rush our team's base. They took damage from those of us trying to kill them, and our turrets - then juiced up and leveled the place. I doubt that's what the devs had in mind. I DO think that Support should get Juice from healing/overhealing other pros and bots at the very least. Without that, there's not much to give a defensive support juice. I'd even argue that perhaps on regular turrets it's not so bad. But getting juice from healing firebases sounds pretty easily abusable.
Supports do the least damage while juiced unless they use their shotgun, and the shotgun has near zero range. Supports getting juice from healing is no less cheap than snipers getting juice from killing bots from the safety of their base without any possible retaliation.
The thing with supports juicing is that unless you have a few going they're largely inconsequential; their hurt/heal gun can barely take down a rockit turret in the span of a juice, so turret destruction isn't much of a problem. The "worst" thing they can do I suppose is go in and hack a turret, though that can be countered by grappling them (don't try to kill them) Overall they're usually slow so grappling them is somewhat easy. I'm a support and I would be in favor of slowing down the rate that we get juice. It's a little too easy to heal turrets and bots coming out of the lanes, as much as it is promoting "support" play.
Uber just needs to balance the Juice gain rates as the Support and Sniper acquire Juice at a faster rate than the rest with very little effort. An Assassin can gain Juice quickly from killing bots and picking up the juice boxes but this leaves them exposed so I can deal with this.
