The real question is: where can we put this feedback to ensure it is seen and at the very least considered by the developers?
We have our Temper threads here, the temper feedback in the test server forum got buried already. Don't know what else we can do other than post some more.
To recap, Spontaneity/Quick Magic recast should be taken down 5 or 3 minutes. Worst case scenario, delete something from category 1 or 2 merits and replace it with the option to merit Spontaneity/Quick Magic from 5 minutes down to 3 minutes.
10 minute cooldown is too much for an ability that seems to be something to be used whenever possible and is not an endurance/survival tool like Convert.
