Dragon link is now pretty much garbage. I have to use Dragon Slash first and then use Gigas in order to get the 15% more final damage. It's not worth it, the time spent using Dragon Slash wastes more DPS, there's no incentive to use it other than to fill up gauge faster, which is only marginally useful in bosses that DR when your Kaiser's Majesty is already used up. There was real incentive to use the combo keys in the old system because of the damage increase, but now you lose out on more than you gain.
The loss of 15% final damage is really disappointing, especially since I only recently was able to solo Hellux and now I won't be able to, but the thing I'm even more disappointed in is the dumbing down of gameplay style. I really liked being able to use the arrow keys and attack keys (my other favorites are Aran and Blaster), it's more fun than no-brainer spamming a single skill key for dps, which is what Kaiser has turned into now, except for the occasional uses of Wing Beat and Tempest Blades.
