For the record I do agree that having more options for us players is always good and I do think your tag suggestion is good. But realistically, the tag favors primarily using kstyle does it not? You're not trying to outright ban SMGs but who will actually join a room with this tag and come in equipping Renard x2 for example? Especially since the aim of the tag is to "prioritize competitive gameplay," I thought it was what you were saying. Either way, having more options would make the room maker set it however they like.
Also I understand you were suggesting a tag, I wasn't implying that you wanted to abandon the customization done by Fgunz. Idunno how you got that from what I said.
I'm pretty sure if the tag was implemented then it would be more popular than lead, infection damage multiplier, bouncy oblivion, FPS, RPG, Weapon Spawn, and Hardcore Mode. I doubt it'll be as rarely used as these ones at the very least.
