Make Dragon Roar require a fixed HP amount instead of HP %

Dragon Roar is an incredible skill that can hit up to 15 monsters. It is very good for farming monsters, but is balanced when it comes to normal DK players because it cost 30% of your HP.

A normal DK player has 30k HP with hyperbody, and this results in roar costing 9k HP per cast. The cost to heal 9k HP per cast plays a big role in balancing out this skill.

It has recently come to staff's attention that beginners can level up with low HP, then job advance to dark knight to take advantage of the fact that dragon roar requires a fixed hp %.

Example beginner DK has around 2.5k hp, so each roar only costs 700 HP. It is much cheaper to heal 700 hp versus 9k hp, making beginner DK able to farm for very cheap.

If Dragon Roar was changed instead to require a fixed amount of HP, lets say somewhere between 5000 and 9000, the beginner DK would cost more to run than the normal DK. The 30k HP DK would have the best dragon roar, as they could heal the most HP for the cheapest cost.

At the same time, I would also suggest to remove the limitation that dragon's roar cannot be used when you have less than 50% HP. This would give actual DK players more options to control their HP to maintain specific levels of zerk.

After implementing this, beginner DK players will either become unviably dead (they won't have enough HP to use dragon roar) or become incredibly expensive (using 1 roar depletes nearly all of their HP).

As a result, staff can remove the new restriction added in the february patch, that beginners cannot job advance past level 29.

If one is to argue that beginner mages are a balance problem that needs to be purged, then it is hard to also argue that 30k hp range characters are NOT a problem that needs to be purged. Its just HP washing, which every class can go to extreme lengths for, we even have 30k hp and 30k mp warriors in this server. Beginner mages is just the mage equivalent of getting 30k hp on range DPS, at a much higher cost.
