Actually is it more as 3 Button.
What am you trying to use in the around 30 seconds of the burst Mode?
-finishing the standard rotation 1 whole time, what are around 6-7 Buttons,
-using all the extra skills, that are: 3x Natrond, Maybe wyvern jump, nidhoog summoning, high jump + mirage drive, Star drive+ Star cross and maybe the twin dragons, if they are ready. That makes 10 skills. Together with the rotation are you trying to use around 17 skills in this small window. And in addition comes dodging of enemie attacks and so one.
The people complained, that the dragoon was to busy and maked fun about it, that one goal of the rework was, to take care of it. But the 7.0 Version maked it even busier.
The removing of 2 Nastronds isnt much. But at last is it a start. And when i think about it, that i sometimes even forgot to shot the second and third one, is the change something, that whe can at last trying to do. And see than, if its fit or not (i was at first a Fan of the Geirskogul change, but than noticed it, that it doesnt feels correct, because, i want mostly to start with the skill, but didnt allways want to start the burst, up to date does it feels, as if it would be better, if a other skill is starting the dragon soul mode).
