How To Balance Medkits (In My Opinion)

I mentioned this idea in another thread that I made, but I wanted to isolate this idea specifically just to give it a little more focus.

So, it's my opinion that medkits are posing a very specific kind of problem in this game, and it's self-heal speed. Not the speed of healing others, mind, but just for healing yourself- if two survivors are dragged off a generator to heal, I'm okay with them having tools to make that departure more in their favour, time-wise. This is aimed squarely at being able to heal yourself at supersonic speeds and undo a killer's pressure in like, eight seconds.

Medkits are a big part of that, especially now that CoH has been toned back to merely 'too strong' instead of 'absurdly broken', but they're also basically a requirement if you're not playing with a group; you can't always rely on random teammates to heal you, and while you normally do still get healed by randoms, there are key moments where you can't coordinate that and a good method of healing yourself is essential. Medkits are and have always been the best tool for that, and I don't want to take that away from solo-queue players- but something clearly needs to be done.

So, what's to be done? How do you balance the necessity of self-heal sources against the problem that having those sources be too fast causes? It's simple: Slow them down, and buff their charges to compensate.

With that in mind, here's my suggestion: Medkits have way increased charges, but dramatically reduced healing speed increases. When healing yourself, I think somewhere in the realm of two to three heals for a mid-tier medkit sans addons, but a negligible heal speed boost- if there's even one at all. Healing others can grant more speed so they're still useful for doing that whenever one chooses to, but for healing yourself, the tradeoff is high charges for basically no extra speed- no penalty, but not much in the way of extra speed either.

That way they're still balanced compared to other heal sources- it stacks up favourably against Self-Care in terms of speed but you will still run out of charges, and it stacks up neutrally against the totem-based healing perks because it's slower but there's no requirement before you can use it. It's also not too unbalanced from the killer's perspective, because repeated heals is not a problem so long as they aren't super-fast heals.

What do you all think? Did I miss something that'd make this less of a good idea?
