I suppose it depends on if the level 25 is a race/faction/sex you want to play. If it is, it's not going to be hard to pick it back up--especially if you have a higher level character you can transfer gold from to get a few pieces of essential gear (bow/gun, particularly) until the quest and drop gear come rolling in.
If not, it takes, what? 3-4 days playing part-time to get a hunter from 1 to 25, so it's not like it would be a great chunk of time or effort lost to start anew with a different toon.
