They all share the same timer now...why?
With the timer increased, why did the cast time not go down?
These spells were not very unusable at all, 90 second recast with a 45 second cast time, makes it even more so.
30 second recast with a 10 second cast time seems more reasonable. I mean 10 second cast and boom it's done, not ten seconds with an additional 35 seconds included with the effect to go off.
