hmm i dont think those favor items that let you 2v5 or 1v2 should be allowed unless the game somehow recognizes that the teams are unfair.. i think that could only work under certain conditions
Teams A and B are equal in player number
only level 1 items availabe
Team A has one player less than Team B
Team A has access to level 1&2 items, Team B only 1
Team A has two players less than Team B
Team A has access to level 1,2&3 items, Team B only 1&2
Team A has three players less than Team B
Team A has access to level 1,2,3&4 items, Team B only 1,2&3
Team A has four players less than Team B
Team A has access to level 1,2,3,4&5 items, Team B only 1,2,3&4
something like that to keep it balanced
