Before T4 introduction there was much focus on (lack of) ranked matchmaking system. Now T4 OP discussions dominated the forum (and not without a reason).
Just as kind reminder and open question to developers/TRS: let us not forget about this feature, please (ranked MM). Whatever the balance between monster-hunters is, well implemented ranked matchmaking calculated separately for monster and hunter roles, should virtually equalize any balance inconsistences. Done once - should work for any current and future balance issues.
(this is not to say, that balance is unimportant; but without reliable MM algorithm any balance issues are twice more painful)
