Anyone who has recently played a ctf game against a lvl 20 knows what I'm talking about. If someone gets a FB+VS+Leap combo off on you, you die before you have the chance to react. No other build comes even close to this amount of disgusting effectiveness. 20v20 fights comes down to who gets their FB off first.

The biggest problem is that for 6 skill points, you can get these three abilities, but any build that doesn't include these three abilities doesn't even come close to the amount of damage output.

The other problem is that a fully ranked lesser ability will not only do less damage, but also cost more health, and on top of this, requires you to spend multiple skill points on one ability. The idea of increasing percentile-based health costs is ridiculous. When we're all level 40, and have multiple rank 4/5/6 abilities, its going to take away over half our health to cast our abilities ONCE. If this trend continues, then at level 40, every build is just going to be lvl 1 dark binding, lvl 1 Brimstone, lvl 1 Ghost Strike, and lvl 1 fatal burst.

Currently is it overwhelmingly inefficient to rank up abilities. Once hp values are higher, the increase of damage is going to LESS than the increased in health cost.

So basically, you can spend three points in Unholy Force, or for those same three points, you can get Leap. Leap does more damage, and costs less health. So what's the point of leveling up abilities?

INCREASING BLOOD COSTS NEED TO BE REMOVED

Now lies the issue of the inefficiency of ranking up abilities. As it is right now, it is always better to just get the highest level abilities, since you'll end up getting more damage and better side effects for less points. My suggestion, either increase the amount of skill points so that way we have enough to make lower level abilities equal in value to higher level ones; or to lower the amount of skill points, and removed the ability to rank up abilities (except for passives) and instead make abilities scale with your level.

If things remain as they are, this problem will always be there. Right now its Leap and Vermin swarm, later it will be Dark Binding/Brimstone/Ghost Strike. The skill tree is sparse enough, but the current design ensures that the same build will be used by everyone that wants a chance in PVP.
