The only thing I don't like about this is the charges on the weapons. Why have it? This doesn't need to be a GP sink and if you're basically guaranteed the drop before your next kill, what purpose are the charges for? Is a rat focused weapon really so strong you need charges on it? Rats are not something you kill often later in the game.
Everything else is welcomed, it would be a good entry to hopefully teach newer players or players that have never done PvM before some of the basics, and I like the idea for combat XP rewards for a more intensive training strategy.
