You could probably argue that those Dragon Blood's 20 points could be spent on....well Sacrifice (useless, but albiet useful in some ways) or PA Crusher. But seriously, those skills are not as useful as Dragon Blood.

Dragon Blood is basically the Dragon Knight/Dark Knight's form of the Crusader/Hero's Rage skill. In fact, it was probably the best attack buff for any 3rd job class in MS (and any jobs out in MS) at that time, until surpassed by 4th job atk buff skills (like Enrage and Concentration) and change of Rage's effects from +10 atk to +12 atk (when maxed).

Now look: Why sacrifice a buff that's given to you, why sacrifice a buff that's actually gives you good effects at a tiny cost, why sacrifice a buff that has no limitations (in terms of not having it run out at any time), unlike War Elixirs, which has to be restocked from time to time?

I can see your arguement about how tiny the cost of using War Elixirs in terms of every hour.

BUT............

For people that are short on $, that skill can pretty much help them out. I know that Stereo's not one of those, but just to point it out, it can save some good $ over a period of time. I can point out from personal experince that I'm one of those that was short on cash (last time I checked before I quit), and if I ever came back, I would try to level as fast as I can so I can get that skill and not have to use Warrior Elixirs regularly, (maybe keep a few War Elixirs handy for certain bosses) therefore saving myself a bit of $.

In conclusion.....

Cost of using Dragon Blood and occasionally using War Elixirs in bosses (when necessary) is much cheaper than using war elixirs every single freaking time, during training and bossing.

MW30 + level 15 Enrage...I want MW30 so much ;_;
