Can a CS team win major with abusing negev or m249

Title, I have never played cs btw just a question out of curiosity

no

It would be more of an uphill battle, but if there was a solid strategy built around it then maybe.

I think the negev is genuinely underrated. Bullet penetration tends to be kinda broken at times in cs and there are plenty of spots where spamming would be good with a gun like that. The only pb is that whilst the negev is decent, the m249 is absolutely unusable. I think CS players are too stuck with the classic weapons but there are maps where the negev would we worth it (it also depends on the map pool a lot cuz some maps it's just unusable).
XM should also be used more but the mp9 fucked everything up by being too polyvalent for too low of a cost.
You can't abuse those guns like in val tho

Negev is 1700 cost, Odin is 3200 cost

Negev was never meant to be a replacement for a full buy

As it takes time to be laser accurate, the player will get demolished by set plays
The only viable option I can see is 1v1 open post plant that also after knowing where the player is

probably not cus like they arent as op as odins
