That is very true...it was not an RP exclusive question or even intent
I am a huge fan of shapeshifters myself but these guys are a bit much.
Maybe if the way they were described were the top tier, best of the best, #1 and #2 of the entire species/race...that I could get behind...and that would make some sense.
If this were a consideration for PC I would certainly consider a shapechanger but there would need to be some checks and balances...maybe something like absolutely zero force abilities, their fluid like minds are too alien to tap into the force directly (so no Jedi or sith)...the shapechange aspect would be wide open with consideration of specialty skills, such as humanoids, flora, fauna, static objects, machines (look like a machine not function like said machine), or element (look like a pile of stones or a puddle of water etc.)...regeneration would make sense with consumption of organic material...etc. There is lots to work with there.
Fun times
Well.... Shi'ido could definitely be Force-sensitive (in canon, not necessarily RP), as evidenced by Belia Darzu. However, I doubt they could transform themselves into puddles of water, as they still have bones and tendons. They are stated to be able to appear as rocks and trees, though.
A few more things that show how powerful (or OP) the Shi'ido are:
They can appear as a Whaladons (another awesome sapient species).
They possess a strange type of telepathy to cover up mistakes in their transformations.
It is very difficult to use the Force to influence them.
They can store items within their bodies and can even transform with these items inside themselves.

I have amended my list!
1. Shi'ido
2. Ssi-ruu
3. Whaladon
4. Thisspiasian
5. Pau'an
The Enzeen bit the dust as soon as I remembered about the wise Whaladons.
I suppose this brings us back to the topic as well
