I dont know how i feel about this, being able to dispell cross CC on both your DPS while you're getting trained seems kinda OP
I don't think it works like that.
The 12 second cooldown will most likely be triggered by the 2nd charge. So it's dispel 1 used. Use the 2nd charge whenever, waiting 12 seconds. Meaning you can use your dispel once on cc category #1 and the 2nd on cc category #2. If i'm not mistaken, there are only 2 amounts of cc dr category's. Which would mean, cc's wont ever last it's full duration if played properly.
Bad feeling about it, but hey -> who know's.
I rather have the old RNG dispel again and make it slight cost more mana then before so it's not a purge fight. Don't make it like mage spellsteal make it 20% of it.
