Charlie, you've listed alot of those weapons there but there are more weapons that have never been used I've checked on www.soffiles.com for different weapons, looking for weaponskins.
There are around 5 weapons that most people have never heard of. Wouldn't it be fun adding one of those new weapons that never been used before?
The only weapons I didn't include in my list were the 4 other frag nades and shotty because you get this at start. The other frag nades wouln't be necessary to have, or we could replace the SMOHG92 with L2A2 which has never been used before except on some DM servers. Or we could just use all of them if you want, but each nade should then have low % probabilities, cause if you put all those nades together in total % there will still be a great chance of a NADE drop.
