I think Sogensara got a little overnerfed. It's essentially a bad deluxe version of Yukijin.
Yukijin has 9 power, 80% accuracy, 0 critical and 10 weight. 60% STR 40% SKI. It's a 7*.
Sogensara has 11 power, 80% accuracy, 0 critical and 15 weight. 60% STR 40% SKI. It's a 9*.

The difference is 5 weight, which "helps" (not really because remains materials and weapon additions) with two-hand, and two power.
These small differences for a world of trouble in finding the weapon if you're farming for it on your own.
To delve further in, lets also compare potentials.

Yukijin's potential changes the damage of sheathe sword to magical, and gives it a specific element instead of being slash damage.
Sogensara's potential targets Doriads and plant monsters (it says enemies, but really..), and lays down ice tiles otherwise.
Sogensara's potential is super situational, but even in the situations where it comes in handy, it's pretty bad. 3m to freeze a boss, or 3m to freeze a Doriad in PvP (when I haven't really even seen Doriads around much).

I have a list of changes that could be made. They're independent of each other.
1. Sogensara's power goes down from 11 to 9, but it's scaling is changed to 60% SKI and 40% STR.
2. Everblue becomes able to target any player, inflicting Frozen lvl 10 and also goes on CD for 3 - 5 rounds. Additionally, it deals damage equal to 75% SWA + Ice ATK as an autohit that procs evasion. It isn't effected by elemental buffs.

Numbers are subject to change, but this is really meant to get the conversation started.
