He never outgrew the "sure, you can play X" and then a few weeks later saying "on second thought, I don't like X. Change your character." Which is frankly bull pucky unless the character is disruptive or broken. You deciding you don't like the idea of a druid, or a bard with 8th level spells, or a shadeling (in a planar campaign, which it was written for!) weeks after you allowed the character to be played is entitled and immature.
The only difference is that he doesn't hide it by intentionally killing your PC and making it look like a random death.
