bumping this because admins gave a non-answer
I really mean this in the nicest way, and im not trying to be rude by saying it, but i dont think it really matters whether you think its not a problem or not. the people who play x100 (and from what ive seen, this extends to x1000) see this as a problem, and by any definition of the word, it IS a problem. whether the weapon stats are updated or not doesnt change that -dmg doesnt work, which makes half the weapons do absolutely nothing or makes certain classes completely unplayable when they werent before this patch. x100 has become a pretty dead gamemode because of this. even all of the fun stuff that players who were new to the gamemode would do doesnt work anymore (like soldier with the whip, which used to deal negative damage and do a lot of negative knockback, flinging players into you, and now it does absolutely nothing). some weapons that didnt deal damage at least did knockback before the patch. theres nothing fun to experiment with anymore because most of the weapons just dont do anything at all. theres nothing keeping people playing the gamemode unless they enjoy stomping the whole lobby as one of the two or three classes that were unaffected by the patch and are now completely overpowered (kunai/amby spy, overheal fan/arm scout). whether it was caused by an exploit or not, it was still intended to be used in this gamemode, and the absense of that ruins it.
Sure, you can take this as a suggestion rather than an issue report i guess, im not one to tell you what to do, but i HIGHLY implore you to fix, or at the VERY LEAST look into these issues so that this gamemode doesnt become completely dead.
