So is there any correlation between the two? - let's have a look at the numbers:
Part 3 - Premiums and Platoons
People in Platoons: 928
People in those Platoons, also in a Prem Tank: 340
that's about 37% - way higher IMHO, than the amount of premiums driven by the general population.
Actually lots of the non-prem tanks in platoons were T-15 armatas - I was tempted to include those in the 'prem' class - cos they are decidedly OP; but i resisted.
So it seems that those Stat-padder munchkins are of course racking up every advantage they can get to the detriment of Glops MM
(not in any way a suprise)
