Nothing much to say here, other than, say in some wargames like World of Tanks (duh), it seems like they don't allow a 3 man squad without a counterbalance on the enemy side. However, there you have like 15 vs 15 (if I'm not mistaken).
In current state, one or even two coordinated players can do little against a premade of four (which includes often a dedicated healer, a sorc kstealer, a procblade and your free spot) of same skill level. Of course at the current moment premades are punished by the broken queue time, but when this is hopefully sorted out...
What is worse, I do not see how to solve the problem. Make 4man fight only other 4man may ruin the queue for them indefinitely. One option would be to introduce a disctinct ``torunament'' mode 4v4 (with no third side), with disallowing 4premade vs random in normal queue. Any thoughts or ideas?
