I don't like how people with low expertise/skill get discouraged to play Ranked Warzone. Purpose was to stratify players according to this, so recruit ppl can play vs recruit and have fun, bm vs bm, wh vs wh, and ofcourse depending on skill: casual, average, decent or PvP god. So it would be good if everyone play at least 10 matches to gain some rank, after that system will match you with people of your class, and imho will be more fun for everyone if playing against roughly equaly geared/skilled players. 10 matches may be a lot for someone to be ganked constantly, but pls pls don't let that discourage you.
Precisely matching you with balanced opponent makes Ranked Warzone superior to regular, thus more enjoyable, besides being able to queue with 8 ppl and pick composition of classes that are actualy needed in well formed PvP group.
