A new MVM update is going to be like kicking a pile of decade old junk just to find a wasps' nest there. If you know you know, MVM players, specifically the tour of duty players (The paid version of MVM with loot), are some of the most downright detestable troglodytes in any gaming community let alone TF2. The years of complete neglect of official MVM, piled on top of TF2's general abandonment has made it a breeding ground for mental illness. If you're not a complete psychopath (or just incredibly stubborn like me), the jihad levels of back-seating, holding lobbies hostage, cheating/anti-cheating wars, group vote-kicking abuse, map exploits/game breaking glitches, cliche-y group policing, and off-site harassment is a massive filter and most people never complete a tour. Until recently (relatively considering this game came out in 07), people could join spectators in lobby and have kick immunity with names like "idle for loot", forcing you to 5-mann or requeue. The 1 janitor (bless that fucking guy's heart) that actually fixes this game pushed through a lot of fixes but the experience is still a dumpster, just not on fire and more so smoldering.
I say this as someone with 400 tours in 2 cities, the easiest way to set off any of these spergs is to have no clue what you are doing, it will send them in a fit that you don't know how to play this decade old gamemode to their liking. I can't think of anything funnier than these discount bossmanjack gambling addicts having new content in their slot machine only to be flooded with noobs ruining their loot per hour metrics. Most of them already queue in groups from years of catty in-fighting, but for those don't or can't fill a full lobby I eagerly await a new era of salt.
Also is there a thread on MVM players? It'd be a shame if none of that was documented, I might have to if not.
