I don't know if it already been posted but i'll do it... ps:
When door of GW are open, you can attack them without removing door HP and when u run cylone, you could start to run a sencond one nearly before the 1st finish.
By this way, you can lvl phoenix faster and with unlimited cyclone (juste have to start it again and again).
I hope i have been understand... sorry for my bad english !
