Dimension Creator wrote: Wonsulsa should be the same as those two but Baam was able to use Wonsul and then later use regular shinsoo... This one is already false; Wonsulsa and Dansulsa are both quite different concepts from Hwayeomsa and Jeonsulsa. Wonsulsa and Dansulsa are more "how" one manipulates Shinsoo, while Hwayeomsa and Jeonsulsa both alter its properties.

Moreover, there is already a case of Regular who would benefit from not using Hwayeomsa if it were possible: Yihwa. Hwayeomsa may have some strengths (as well as weaknesses) over basic Shinsoo manipulation, but it's apparently very difficult to control, and Yihwa has repeatedly demonstrated her inability to properly control her flames in the past. Seeing this, why on earth would she continue to use Hwayeomsa she cannot control--and that has ostracised her from any team with which she climbed--if she could simply turn it off?

In case you're wondering, the Hatsu example is a false analogy, so I haven't gone into it in depth. In any case, this is as far as I'm willing to go in this discussion, because--while everything points to what I mentioned--it's not set in stone per se.
