Not sure if there are better options, but taking a glance through warrior weapons, you could get something like:

This means you can get an OK ratio weapon + some worn haste. You're looking at a 0.67 ratio with that setup.
You should be able to kill mobs that give you experience from level 50-60, even if you have to resort to using Evasive disc on each mob, and basically AFKing between cooldowns.
