We are now approaching the Ball, and that's good. I'm excited to see what data points they've compiled for us to discuss and reflect upon. That being said, I think it is important to note that Shai did receive a significant nerf, and when other classes rose to see similar numbers, the devs chose to nerf the spot instead. This was perplexing but Shai was given a healing skill. This heal is very helpful but I do still believe we could use some survivability.

Healing doesn't do much if you die in three shots.  Heal skills have cool-downs.  Can't really spam heal to survive. And I bet a Musa barreling in could decapitate a Shai quicker than she could hop away and do any healing maneuvers...

Also, amazing work putting together those charts at the beginning!  And that Zerker/Shai cartoon: love it!

In my opinion the class needs divided Succession/Awakening as any other class, expanded kit, increased ratios (especially Mystic/Striker), more mobility (through expanded kit), and definetily more protection. Shai for me seems very unprotected and at the same time unable to do damage. This doesn't make any sense. Especially in a game where super armor is pretty much spammed in.
I would also suggest Forward Guard to Try This! skill.

I wholeheartedly agree with the OP. 

PA, please hear our discussion. 

yes pls. Give us a passive that works with our builds. A nice passive like striker and mystic have would be awesome! people complain that they cant kill Shais, but Shais just survive if we put every damn GS point we have in DP and especially evasion. A Striker with that gear would be unkillable while still being able to do some dmg and has more protections etc...even a Archer would be the same kind of tanky with our gear, cause our tankyness is 100% gear and 0% our class.

We should gain tankyness in the same ratio we lose dmg in PVP. And maybe make Shai unable to use an axe so she we will never get the problem that she can chop down forts alone over time.
