I understand the complaint very well. What I'm saying... it doesn't matter.

The results are:
  • Players are playing other tanks still
  • Healers are still playing healers
  • Parties are clearing dungeons/raids/etc

Even if BW is OP, it hasn't changed any of that. If people are backing out of parties because there is a GNB/DRK/PLD instead of a WAR, then there's an issue. Until then, this is just something to complain about with no actual "harm" done.
