Unbanning them won't kill the scrim playerbase. In the event there is a magical amount of fun-killing abuse, then people will just agree to stop using Negevs or soft ban it in agreement beforehand; scrims won't suddenly die because people are incapable of agreement. To "abuse" a Negev, you literally have to echolocate yourself for about 15 bullets and stay vulnerable in a slow, crawling approach to retain its laser accuracy. If players are inept enough to not be able to fire at an essentially still target, they should honestly improve. Negevs are easily countered by waiting out bullets (through smokes/wallbangs/aggressive prefiring) and by not standing as still as possible into bullets which you should be easily aware of if you possess two eyes and ears (sorry @Rabid). In terms of the newer/worse players, they would have likely died either way, and isn't it already not fun to be completely trashed by the better players? There isn't really a noticeable difference in enjoyment until you're able to actually kill anyone, and dying to a Negev, getting one-tapped by an AK, or dying to an AWP aren't very different in that regard. There are far more annoying guns and situations to die to/in, and if anyone were to be genuinely angered by a Negev they shouldn't be playing a videogame which you die to death in. If we wanted to unban them with restrictions, there was literally a gamemode which limited the amount of times a gun could be purchased, and if that's unable to be smoothly implemented there are plugin options.
No money gained for a kill and you deserved to die scrublord, just hug corners less :^)
Is really only strong in one-by-one peeks or weak rushes with low player awareness. The AWP easily outperforms it offensively and defensively, and a worse player who uses an auto would likely end up in a still, vulnerable position. Either way, you're going to die to a scope, run back, or kill them. It's not much different in the role of an AWP except that it allows people more forgiveness for a miss.
Again, +1 to all. Don't BabyRage because you die in a video game :^)
