You have mana, you cast spells, as simple as that. Regardless of if they have a cast time or not, if they are correct for the situation, you use them. I have no problem casting an 8 second repent as ret as long as it means we survive enemy burst or land a kill. The choice is yours. Complain and don't use awesome abilities, or use them and win.
