I feel like ventimus isn't that bad with 3 points into it. 3 points is a lot, therefore I feel like the damage for it makes sense. Although, I do see both sides. Dueling someone who uses ventimus is quite tricky. I do agree with the fact that maybe the cooldowns should be changed. Since the AOE for the spell is quite large, it makes it pretty easy to get hit by it. I noticed that people who have three points it in usually use it around three times in one duel. This can do quite a bit of damage. Therefore, perhaps the cooldowns could be changed a bit.
