I do enjoy how you spend all this time gathering all of these forces to your side over the past 3 games (Rachni, Krogran, Geth, Quarian), and in the end, did any of that matter at all? Do we see Rachni forces attacking Reapers? or Krograns in battle? No, all it did was add to some number so you could get a different color ray beam and earth survives.
Its just a load of crap.
