Can someone just come and explain how the goddamn thing even works now? It makes no sense at all
Put harshly, it doesn't.
If you want to give it a shot: 1. assign your basic "Attack" to a key 2. go to your beginner tab, assign the "Dragon Link" skill (icon is an exclamation mark) to a key 3. press "Attack" then immediately, 4. press the key(s) that come after the plus (+) sign ("SKILL" for Gigas Wave command is whatever key to which you have assigned Gigas Wave) You have to repeat steps 3 and 4 each time to get the 15% Final Damage bonus and extra Morph Gauge.
It's a slow mashing of two or three keys that doesn't work a large portion of the time, and actually drops your DPS even if you successfully manage to pull it off with certainty.
The changes to Command Keys forces players to alternate attacks between the one they intend to use, and Dragon Slash (a 1st job attacking skill).
Not only is the "combo" difficult to pull off for players with high ping to the servers, it actually decreases the average damage output. In addition, the slow rate at which you can "combo" means that the Morph Gauge can be filled faster without using the new Command Keys. The 15% Final Damage boost nowhere near compensates for the extra time required to cast Dragon Slash and press the subsequent required keys.
A revert would be much appreciated; it used to be a core element to Kaiser gameplay and a way to reduce keyboard clutter, but now not one situation exists in which it would be optimal for the player to use it over simply hot-keying the skills. i.e. even if the feature was removed entirely, there would be no change in optimal play; why was it rational to implement such a change in the first place?
