If I'm understanding it correctly, it sounds as if the grievance is that new move additions — namely the TMs and tutor-teachable moves (Outrage) — has made Dragonite more easily counterable, and thus has diminished its power in the PvP scene? Is it Dragonite in particular that you believe these changes are negatively affecting, or do you believe it's a broad range of Pokemon that have been rendered "unsuable" now in PvP?
It wasn't our intention to nerf any Pokemon in particular, as much as to simply make Pokemon more well-equipped to have their own battle potential—diversifying the battle system, which involves tooling the Pokemon's move pools as they are in the handheld games.
Since PWO is still mechanically different than the official games, in the sense that the features are still behind in the full-knit battle system of the official games, plus we're adapting to an MMO environment, changes can be made if imbalance exists in the current battle system. However, in this case, it sounds as if you're isolating Dragonite as being powerlessly unusable with the recent changes.
