Predict some Magician changes.

Not my point mang.
It could have been better if they just made dragon's blood stack with hex. Not give you a worthless 60 str.

Dragon's Blood did, and still does stack with Hex. The reason 60 strength is better is because all other buffs would cancel Dragon's Blood out and that was just a nuisance, but now the Dragon Knight can use Dragon's Blood along with any other attack buff and not just Hex.

If you really want the 25 attack so badly, just go grab a few Energizer Drinks form Neo City in Year 2227. Dunas and Royal Guard Type S both drop them at a 100% rate, and they're pretty easy to kill. Energizer Drinks grant +25 attack for 30 minutes, meaning getting like 10 of them will last you a few days if you don't train or boss excessively, and since Hex stacks with other attack buffs you will essentially have +65 attack AND +60 strength. Before the change to Dragon's Blood, you could only get up to +65 attack. Hell, if you get more Energizers than you need, then you can sell them for up to 200k each and make some quick cash. Then you can use that money you earned to buy an Onyx Apple so you'll have +140 attack along with that +60 strength!

My point is this: The change to Dragon's Blood doesn't nerf DKs in any way because now they can use Dragon's Blood to POTENTIALLY obtain even more damage than was previously possible. If you just use Dragon's Blood and Hex on their own, then yes it isn't as good.
