Given the smal size of the Shai, and how large the Florang is, I can't see why they should not be able to block front damage with it, just like a shield.

100%

Still baffling how they give classes like Ninja, Kuno, Hash, Sorc, etc pretty much perma-iframe + full SA combo chains + block and they don't give anything really to help the Shai survive in PVP. 

PA should be ashamed at how much they have screwed the balance of this game's classes to eachother. They should especially be ashamed how they forced the Shai community into accepting the role of Buff-Bot who will always die 15 sec's into a PVP engagement.

I like this. I don't know her skills for BDO mobile or that arena game but I do remember there were unique skills. It would be worth looking in what she can do outside of this game and get inspiration for new skills here. Right now she has almost no skills compared to other classes and everyone is sitting on like 2000+ combat points. Defending using a boomerang sounds like a good idea since it would fit her class well.
