99 cap is the final cap, so the fight has to be special and impressive.

As for the new ws, the fact that a fully merited new ws can compete with relic/mythic/empyrean is exactly why they are only allowing 3 fully merited ws, because if you could fully merit all of them it would be more messed up than it already is to players with empyreans/woe/mythic/relic. If more ws were allowed to be fully capped, then the power of these new ws would have to be nerfed, is that what you would want?
