How do you feel about the current multiplayer gamemode?

Recently I've been back to sk, and noticed that a lot of multiplayer rooms is either unavailable or the host just quits. The only room availabile is matrix and level, no badass, no challenges. It's impossible to get any achievement at this rate, how should sk update or remake the mode?
