I disagreed with the sentiment mostly at first, but then I read through the replies and am 
There’s so much here to go through
but I don’t entirely hate the changes you mentioned later in the thread, either.
A sniper weapon is supposed to be able to kill things and I don’t see why it shouldn’t 1 shs on specials without a breakpoint, since getting a headshot is a pain in the butt anywhere with a ping higher than 10. For Elites it depends, I mean a dps heavy class should be able to dome shot Stormvermin; on the other hand this thread is the first time I’ve ever read that a WHC can 1shs a CW in cata with a crossbow, but you mentioned it was a meme build in the same sentence without going into detail so I really wonder if it’s honestly indicative of a problem. Dont get me wrong, I’m not going to argue against WHC not being able to apply talents and passives to ranged, since I lobby for that exact thing to befall a certain Flagellant who’s needing a serious looking at for a good while.
I think the idea of packmasters being unkillable is just wrong on so many levels. I know my pre-made and qp groups suck responsibly practice social distancing, but the idea that hookrats can never die without the whole team unloading on it like a boss doesn’t sound like it would improve the game at all. I already get grumpy when I fail to kill one at point blank with a shotgun and the only time I ever accidentally killed one with a greatsword was as WHC, crit headshot, as host. Never been that fortunate again.
Weapon rats having more health isn’t bad, would honestly make sense for them to have the same as Stormvermin, but I’d want something in return for the added difficulty, mainly to be able to stagger them out of their attacks. I don’t mind if it requires some power investment, but if I’m walking on a flamerat as Grail Knight, or point blank as someone with a shotgun, and I have no choice but to face it while getting stabbed in the back then I want to be able to shield push them or blast them out of their attack.
The changes y’all want for conservative shooter sound like it would be regretted. An internal cooldown would put it down considerably enough. Taking Scrounger (and by extension Swift Slaying) away from crits actually makes a lot of sense. Heck, since I’m on about crits, I’m surprised Blessed Shots has survived all patches so far. Every other guaranteed crit ability for ranged has had problems and much concerned discussions. Blessed Shots could easily just not be a crit and completely change the way BH plays. I’m not complaining, because BH ain’t my main class (and when I do, I want to BoP like John Whick or use the repeater pistol and be sad), I’m just pointing out his passive’s continual survival bucks against the trend (as set by Shade, WHC, and maybe Hobo? I forget but I recall he’s been through a lot). Most ranged damage + highest ammo regeneration has always been kind of a headscratcher that’s been quietly justified by his poor melee.
At this point I don’t even know if I’m going off topic because of how much is covered by the OP. Yes, UC shouldn’t provide team heal. Not the right theme and bucks against the character. Also teamkills via UC ult is rare and hilarious. I feel bad for saying this, but it’s got a flavor of crutchiness. Basically there for comps that really, really want a FK.
I guess Engi’s ranged aura is part of the support power creep, but that requires people wanting to bring him over anything else. I know it happens, but I see just as many people in QP dropping from a group at the sight of an engi in cata. Anecdotal, I know.
As for weapons, crossbow gets mentioned a couple of times a month for being strong. Kind of surprised it didn’t get handled during the last BBB. I know it needs to be different from Handgun and Longbow, but it still seems to cover all bases extremely well. BoP got mentioned and I’m all for it not doing as much damage at long range and even being less accurate, but I think what it does now at close range is perfect, an absolute joy even with that reload thing I haven’t forgiven FS for
