I think having an alt character or characters is quite ridiculous. I can understand how some create them to run raids, that may have 1 drop a week or 1 win per week, create an alt to help friends with the content they cleared on their mains, but there is so much stuff to do on one character: dailies, roulettes, challenge log, etc that it just seems very bizarre and quite perplexing for others to want to have a whole separate character to do that on the alt.
I can do a gaming session of about 9 hours and still not get all I want to get done accomplished. I'm not sure what planet some of you alt hording players live on, but how many hours are in your days and do you have a portable restroom on hand?
I think though, to get on topic, if you want an alt, nothing should be transferred over but veteran rewards, as long as your alt is still on your main account.
