Every time SE alters the game someone feels like they've been gyped in some way. When they lessened the exp requirement 60+, people said that it undermined all the "hard" work they put into leveling up. When they nerfed the Promys, and fixed it so that you didn't lose exp for dying, people said it cheapened their accomplishment of finishing CoP pre-nerfs. When they released ToAU and blms were no longer "necessary" for efficient parties, blms who had been manaburning only for years, and wouldn't give exp parties the time of day whined that it made them useless. People always threaten to quit in protest, but few do.

When you log into the game there's a warning which says you are agreeing to the TOS by logging in. In that TOS it clearly states that the game is subject to change, with or without notice. That is the nature of all online games.

And just for the record, I'm one of the bsts who got all butthurt when SE nerfed MPK. I said I'd quit. I ranted to anyone who wanted to listen (Or not. Whatever, I didn't care because I was pissed, and wanted everyone to know it, whether they wanted to or not). Turns out we were just acting like spoiled babies. Turns out the change did way more good for everyone including us (especially us), than harm. Turns out the world didn't end, it didn't lead to communists eating the world's supply of kittens, and most importantly that nobody else gave a rat's ass.
