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.

I'd argue that it's a disliked and invalid strategy, seeing as the mechanic of throwing the harpoon through the wall is not intentional, and abusing it for cheap kills is therefore an exploit.

I'm not saying remove the harpoon, I think it's a good weapon. What I don't think is good is the harpoon being able to come through walls like the Kool-Aid Man.

I see what you mean and I agree on some scenarios, but I’m just saying that I don’t always see it as a problem. I just see it as cheap tactics require cheap tactics to weed them out. It’s hard to say for sure that it should or shouldn’t be because depending on the context I could see it as valid or annoying, and we obviously can’t have situational exploits.
And as for cheap t kills, most items in the shop give them cheap kills lol
