Endwalker summoner question

[Risvertasashi]

Summoner mobility is overall pretty good. You have only 1.5sec cast times so you can slidecast after 1 second and move 1.5sec after each cast like Astro now.

While that's pretty good for weaving, I'd worry it would have "the red mage" problem - where sure dualcast is great for getting a bit of mobility, but starts to suck if you need to move for more than a GCD.

Whereas current ruin 4 gives you 8 GCDs of free movement every minute (separate from DWT and FBT), and while you do want to have 4 stacks going into bahamut, it's otherwise pretty free about how you use it. So I guess what I'm wondering is if the new summoner will get somewhere equivalent to 8 GCDs mobility per minute that you don't need to be in a specific primal phase for, or if you'll always have to save it for any time you might need more than a GCD or two's worth of movement...
