Nice addition the RP to WOF tickets exchange!
You are right, I haven't seen that before. Is there any explanation how much must be bet to have access to more than 1 exchange?
For now I think each time I roll RP from daily WOF I will exchange it back to WOF.
I bet a little daily althought I'm far from being an heavy better and it says I could exchange 39 WOF tickets per day.
I'd say to you, try to bet a little, even very little, for a week or two and see how it goes.
