the negev in csgo was updated to be just as broken as the pyro was with JI, reducing its cost by over half and changing its recoil pattern so after a second of continuous fire, it had zero spread
ESL and ESEA literally banned the weapon next week because it needed time to determine if this would affect high level play, and it was almost unanimously agreed that it should stay banned for at least a little while despite pro players saying they werent going to use it. its why the most recent CS update was another pass at the negev.
the same situation is playing out here with pyro. it's been updated poorly and made too easy to play, and even though it may not affect the highest level of play, many players including some of the highest level of play would like to see it banned in order to call valves attention to the problem
