What's with SE and balancing

[CKNovel]

Personally, I just dont understand the following logic:

Melee dps must have a higher base potency because they will have less uptime. And so to bring it back to normal level it is needed.

Okay but then SQEX must design content where you can't have +95% uptime.
My maximum number of ranged attack on a clear (as a tank) was 11. I wanted to respect as much mechanics as possible.

To be then reduced to 6, then 4 ranged attacks.
Maintaining melee uptime is in now way hard, especially when SQEX delivers encounters with half the map as a hitbox or full hitbox without positionals.

I do agree with the statement, but not in this current context and raid design..
