I thought Jungle Carbine was on the naughty list? It is literally the only weapon that I can eyeball as the popular tool of my own deaths. Does it still kill with a one-bullet headshot and two-bullets bodyshots?
That weapon was a sniper for Medics without the optics.
It is better than most sniper rifles if you can headshot but it's not very effective at extreme range. It and the Tromboncino are similar guns and I perform about the same with both, only the jungle carbine has more ammo and a slightly longer range that can make a big difference.
They are tricky to use because you need to get in close but they require more skill than most weapons and are fun to use. This patch has made them more viable though since they already were super viable before, even though every 'stat analyser' would tell you that bolt actions were out for the count pre-patch. These range nerfs should make carbines easier to use for the average player as you will be safer further out though as exposed as before in CQC, just as any strong headshot weapon is affected.
I am a bit dissapointed that the Jungle Carbine has invalidated the tromboncino though, I think that gun is the most fun to use. I feel it could use a balance pass that either:
1) switch the one hit HS ranges, trombone at 100 and Jungle at 75 meters. I'd use the Trombone.
2) Nerf Jungle RoF, make machined bolt bring it up to the current base RoF (lower than the Trombone), I might use the Trombone. The Jungle would probably feel bad though (unless you upgrade RoF).
Right now the jungle is better at both headshots and body shots, so there's no reason to use the Trombone which is a shame.
