To make life a little bit easier for the bottom tier tanks

Lert: Everyone knows that feel when you're a tier 5 in a tier 7 match, or a tier 4 in a tier 6 match - the lowest tank in the game. Most people also agree that the current +2/-2 spread is basically ok.  However, there is still something that could be done with that.   For example, being the only tier 5 against 4 tier 6's and 10 tier 7's is not fun.You can't really expect the lower tier tanks to do much in a match if they are the vast minority. We all enjoy the 'many hunters can take down a mammoth' idea, but that becomes very difficult when it's one hunter against 10 mammoths.   So I suggest that in any match where there is a two tier spread between the top tank (for example tier 7) and bottom tank (for example tier 5) the low tier tanks (the tier 5's in this example) would never be a minority. In other words, that the bottom tier in a match (excepting scout MM) would never be less than for example 40% of the team.   TL;DR: Make it so that instead of there being a possibility you're the only low tier tank in a match, there are never less than - say - 7 low tier tanks.
