You guys realize that you can use Lugh Abi2 twice if you reset it the turn before and then hold onto it into the next turn, right? In fact, this is the behavior you should subscribe to by default, esp. when Lugh is about to burst because you'll be able to get 3 hits off with her burst effect instead of 2. There's no reason to use it immediately because you'll never hold onto your reset for 6T to let it come off cooldown naturally.

And Managarmr buff lasts 2T, not 3.
