Remove mob exp loss. Optionally, only remove if there are < 5 people in your group range.

One thing that keeps me from rolling a character is that I get too bored with safe solo ranking, and end up taking risks and dying. If this happens twice in the same level I inevitably will delete. This may be a personal flaw of mine, but I've never felt that exp loss truly adds to the game. With a high player-base it doesn't matter too much because you can reliably power-rank the pain away in a group, but at the current level, the penalty for taking any risk is too high.
