How in the world can 55% teams beat me in a row.
Every one could loose from a -35% weaker team in a bad day but in a row ? You 're doing something wrong in the tactics.

I'm in a huge lose streak currently using 4 3 3 tactic.
3 MC-3ST ? bad formation.

You must upload some game pics with details (formations , orders, stats of the game, rates, actions you did during the game) so to spot what went wrong.
