I can't let this post go by without saying something.... This game didn't DIE.. it was shut down by NCSoft. The game was still making money and still popular. It did NOT die, just because you didn't understand something doesn't mean the original dev team was lazy and your misunderstanding is why this game was shut down.
I'm sorry you had a bad experience, but the red side AT's (MM, Corr, Stalker, Brute, & Dom) were originally designed for players with more experience from blue side. Original heroes who had characters with pets knew that enhancements did not affect the pets in the same way that they affected the player's character calling the pet. My first 50 villain was a Bots/FF MM. So the AT did not BREAK the game, was not poorly designed, and there was no need for outrage from the player base. In fact, during beta testing of City of Villains, of which I was a part, the player base helped improve the AT and gave very good feedback about all the classes.
