Please don't add Chainsaw or Remote grenades to the server. Please... those weapons are the most noobish weapons and adding them will just result in suddenly everyone abusing Chainsaw / Remote in close combat which in turn will lower average skill in VCMP because everyone will see and use those weapons as an alternative to shotguns.
So should we remove all weapons that are easy to use? Spaz, M60, Molos, RPG? That'd turn boring real fast. Sets can be limited to 1 person per team just like the rpg pack, if they're too overpowered, that is.
If the chainsaw is to be added to the server it will be added as a new pack and not as an addition to any of the current packs. The molo pack tho underused is actually really powerful if one knows how to use molos correctly, adding the chainsaw to it would make it far too powerful. In my opinion, molo's are the best wep to fight with while outnumbered, very easy to defend bases with those.
There's a huge difference between the weapons you've mentioned and Remote Grenades and Chainsaw - really.
Here's what you can do with remote grenades; if losing in close combat you can pull them out, throw one, bomb yourself and the enemy; both of you will get knocked down and there's literally no way for the knocked down enemy to stop it.
There's literally no way to stop, counter this playstyle - while every other weapon you mentioned has a counter; counters that are, well.. quite obvious, so I won't mention them.
It's more or less the same with Chainsaw - fighting in close combat? Oh, look, I'll pull out a chainsaw and saw you to death in less than a second. Hey, you'll do the same? Well I'm on 25 fps average and you're on 60 so have fun with that! Yes, sure, I agree that Chainsaw is slightly more counterable than the case with remote grenades, but still... please, no.
If yes, then at least add them as a set with only Chainsaw, an SMG and a pistol - no shotguns. Please...
