I'd be happy if they added Flash and Bloodbath to cross role actions. I did Antitower today for a FC mate and I'd say Flash was really useful in that dungeon due to adds spawning while you're tanking trash already. It's possible to save Steel Cyclone/Decimate for it, but if I have the gauge, normally I'm going to use it. And Rampart is highly inferior to Bloodbath for trash, especially for large pulls (Decimate is really good paired with Bloodbath and Berserk).
