This exploit pretty much goes against why we have that damn roulette in the first place. I had a friend rejoin the game and he wanted to wrap up Dun Scaith. We were in the queue for well over an hour and decided to give up. As a last attempt, we tried the roulette and prayed, and it threw us right into LoTA. I seriously lost me marbles.
I don't know how SE can address and fix this, but the roulette is NOT working as intended. I will gladly take a nightmare run of Orbonne over any of the Crystal Tower raids at this point. The only thing I can think of is placing a ilv requirement based on your current level to even queue up for it. As an example lv70+ players would need to meet the requirements to enter Orbonne to use the alliance raid roulette. That's probably not the answer, but all I can come up with. I'm still steamed about last night to put any kind of constructive thought into it.
