From DDO wiki
what I miss here is:
what happens to VIP players becoming premium f2p? what if you had 10 character slots filled up?
- From reading the forums, it seems that you have to choose from your charcters, which ones you will be able to play. The remaining are locked untill you increase your slots again. Similarly any feature that you do not have unlocked such as warforged will prevent you from logging in. I haven't verified this as I am f2p, but if someone can, could be nice to flesh out the article. --Cyanpill 11:57, November 27, 2009 (EST)
