T4 is the most deserted tier to fight, yet on prime times there is no problem to find match. Problem are sizes of those matches, rarely being greater than 5v5. Combined with nature of weapons and modules (long ranges, very high damage close, high durability of ships) you have hell of leveling. Often these matches end with less than 1000 points resulting in around 6-10k synergy. There should be greater bonus for wins here.
due to the new rating system T4 is at a good playerbase
The playerbase is spread on all tiers
