Care to elaborate? I was under the impression that these solutions would keep certain players from amassing hordes of wealth (based on luck, especially) and ruining the market. If you mean player outcry would ruin the game, sure, some angry players would leave--however, it would solve problems that keep new players from staying around.

Ultimately all players are going to get upset when Three Rings puts out a new update they don't like (crafting cost, bound items, etc), but I imagine it'd keep the game alive. Not sure how it would kill it, instead.
