So you've always been curious about that Combat Medic (CM for short) Talent Pip has. People don't tend to rave about it, often ignoring it for the already-unlocked-by-default Mega Potion (MP for short) talent. This is in part due to MP being fairly potent; 2000 near-burst healing in one throw is nothing to sneeze at, especially with cards that make you able to use the potion more often when you hit allies. CM by comparison does 750 per shot (4500 for a full clip), which sounds like a lot less if you only heal with your potion launcher, However, many people forget (intentionally or unintentionally) you still have a 1000hp potion to use! which of course, also takes advantage of any loadout card Mega Potion can use. I call this a hybrid style of play, and I've found it to be far more effective than solely relying on either MP or CM by themselves.

MP is limited by the healing per second (cards have internal cooldowns, so you can't abuse the "Reload" loadout card constantly), but it does do a lot of healing in that short time (up to 4000hp within a few seconds), but again, cooldowns are a factor, and Chronos can only do so much to alleviate this issue. However with CM, you're free to keep healing whoever's in front of you until you need to reload. And when you're reloading, you can just throw out a healing potion, reload, then throw out another healing potion, and then keep shooting and healing again, and so on, and so forth. So CM does have its advantages, if you're willing to work for it.

The best way of describing positioning of Pip with Combat Medic is this: Reverse Flank. Don't stay in one place for very long, always keep moving, but always in line of sight of your frontline and other players so you can heal them. Be hard to track down, climb high up and heal, get back down and heal, just be hard to pin down. Heal anyone and everyone in front of you, your range is only limited by Pip's arc for his launcher (it's about 3000 units, but testing this is very hard to do) and his potion arc (also very long and hard to test, but likely in the 4500 units range). Anyone who gets healed by even 1HP by your main potion will contribute to the cooldown reductions the below loadout uses. In an ideal situation, in about 5.5 seconds, you can heal 4250hp (one potion, three shots, then another potion), reload, then an additional 3750hp on top of that (5 shots of 750hp) while your cooldowns are still off. In reality, the numbers are likely going to be fudged due to cauterize and, well, you're not entirely a robot, so about 4500hp - 7000hp within about eleven seconds is probably more accurate a guess (again, cauterize will make the number go down).

Added during Radiant Stars was the CM-specific quirk of knockback being removed from the potion launcher while shooting, and shots no longer damaging you. The latter was especially problematic when you were healing up close when your potions were on cooldown (as you might imagine, this is completely antithetical to the playstyle as it damaged you while you try to heal your allies). Despite the upsides, there are people out there that consider this change to be a nerf, on the grounds that it removes knockback-jumping. Knockback Jumping is basically the Diet Cola Lite version of Rocket Jumping, only less useful in every possible way. It's a seldom-used technique that lets you get to slightly-out-of-reach spots on maps. Not only does this technique require knowing how to pull it off (which requires practice, and yes, does technically raise his skill ceiling), but you've gotta know where you can do pull this off too, which isn't in as many places as you'd think, as it won't help you with jumping on top of the tall architecture Pip will never reach, regardless of technique. Our fluffy boi is already able to get on top of pretty much any mid-ground on a map anyway. So Knockback jumping isn't that helpful, and the benefits of not being damaged for healing someone severely outweighs the downside of using a niche flanking technique on a playstyle that isn't trying to get ahead of the enemy, you're aiming for Line of Sight, which restricts where you can move to anyway. This leads me nicely into how to move as a CM Pip.

Oh, and don't try and fight 1V1's... you'll likely not win them. Your kit has been made to heal more than harm. You're basically a healbot, but that's part of the playstyle; maximum healing attention for decent results. I personally like the effort, as it feels like i'm helping (maybe i'm just dumb), But i'm not against making CM have more healing (750 -> 850hp per shot)
