Reading through the forums I have seen several posts about people wanting to reroll characters, and this confuses me. I am an altaholic myself, and I spend my time spread between 9 characters, the 10th being our guild bank alt. I might even say I have more alts than that, considering the two I created for It came from the Blog. What this means is that when I log in, I choose a character to play based on how I am feeling at the time. Sometimes I feel priestly, sometimes I feel the need to rage against the world.
But back to the concept of rerolling. Rerolling a character, as I understand it, entails completely deleting the character you have been working with in order to start anew. I have had friends that did this, one in particular that deleted his hunter in favor of a priest, only to regret the decision later. I asked him why he didn't just leave the character since you have 10 slots to work with. The only reply I got was a /shrug.
