I think it’s fine imo. It helps counter people doing things like door spamming or hiding in unreachable places. Of course there’s always the alternative of the C4, but that takes a timer and beeps to alert the victim. I say don’t give the camper the out, the harpoon through the wall is fine.

So instead of letting people utilize a legitimate, though unliked playstyle, we take advantage of the harpoon's bad coding and get a ridiculous kill?

IMO the Ts have enough tools at their disposal without the harpoon to kill/wound/send into panic the innocents.

Well it’s not like it’s just instant kill like a knife. The harpoon still requires some skill and cunning. I’ll admit there’s lots of opportunities for cheap and stupid kills, like through t room glass, but to weed out most situations with it it would require knowing where they’re at, which isn’t always an easy thing to do, and hitting a target that knows it’s being hunted is usually a task in itself. It’s arguable that it’s a disliked yet valid strategy to use the harpoon through walls. I know it’s no an intentional mechanic, but it could be argued by the same principal. 
As far as T weapons in a general speak go I think some of the things that should be focused on are things that don’t require half what the harpoon does, like the knife.
