Well if those arent areas the map developers intended for you to get to, that you need special equipment to get to, then they are exploiting, as is this.

Explain to me why nobody ever complains about people using the grapping hook (the very definition of special equipment) to get to places like the inaccessible rooftops on terrortown or even the top of the really tall twin tower on the original rooftops map, they're both areas that the map developers never expected people to be able to get to because they never accounted for the fact that people would mod grappling hooks into the game.

There's a line between an area you can only get to by grappling hook is an exploit or not. Those specific places you can still kill whoever is up there from. You can snipe in both places. The airship is different because it's difficult to snipe due to glitchy helicopter physics. Also T weapons don't reach there. That's where it crosses the line to becoming an exploit because they can wait out the round time that way and win.

Manhacks would reach it. I think a C4 would reach it but I'm not sure (test it maybe), a T using his own grappling hook would DEFINITELY reach it. The helicopter is not as glitchy as you think it is, the bigger problem is the hitboxes not registering when you shoot somebody.
