Hello,
I think, there is small issue with OL player gaining 3 XP after finishing his/her deck. It's much simplier playing only Descent JtD + SoB than having all cards from all expansions. Either OL should get e.g. 5 XP or the deck should be customizable and limited to fewer cards.
Apart from this, it's impossible to finish such deck at only one level to benefit from "Running out of time".
Any suggestions / ideas ?
thanks
