I am considering what to boost to 90. On the one hand you could "waste" it by boosting a partially leveled toon, but on the other those might mean more to you if you got to play them. I will be interested if this becomes a paid service.
If I started a new alternate character then it would most likely be a mage or a priest. I have a few other options including druid, monk and rogue all in the 43-67 range. Any thoughts? I'd like to stick with the flexibility of hybrids but I'm also after having a toon of each class.
What are you guys planning on using the boost for?
