They did remove the kick system for a reason and sometimes when a clan wanted to play together and some other player joined, they used the kick system to unfairly remove that player from battle. I partially agree with this topic. Mults and saboteurs get on my nerves as well - I was playing a Farm CTF (50 flags) and someone left on my team. This other guy joins the battle and sits there for 3 minutes doing nothing - luckily we were about 5 captures ahead so they only managed to equalise but eventually he started playing: http://prntscr.com/5z6bgv Oh and this is perfect evidence. You see player general_abrams he used M2 Viking M2 Isida Rustle against a bunch of M3 Mammy/Twins/Taigas. This goes to show, it's not always about the equipment - lower ranks are still very good players but don't have enough rank to obtain their M3 so when a low ranker joins don't say "Leave mult."
Now the crystal update has been removed, I do think there are a lot less mults but people still pushing and barging with weapons such as Vulcan really won't help the game. Vulcan is OP enough to flip a Viking M3 - if it can do that, people will be multing in games to try and flip their own team up. Remember the Violators Section is still here. :)
