Super 6: Season 4 is Open!

Devorantem, on 07 February 2013 - 07:36 PM, said: Only tanks of tier 6 or below and artillery of tier 4 and below, may be used in the championship. Declarations of tank choices before the game are not required. In the event of a team-member violating these regulations, the whole team will be disqualified.
Light tanks will now be limited to 4 tanks per team, this should help prevent any "greifing" of tier 6 heavies and tier 4 artilery Chaffee and similar tanks allowed?
P.S. In game company allows light tanks only tier 1-4. Same?
