Matchmaking times

I really like the game especially marines and predator and the balancing is alright so far maybe im one of the few who think so but what bothers me are the waiting times.
Longer rounds or shorter search times would make the gameplay-fluence better.

I would almost say make a 2vs4 and make the predators weaker to make finding matches quicker but that wouldnt fit into the game and the balance issues would be too big.

What can we do to lower search times?
