Keep playing Kaiser?

I originally made my Kaiser because of a few features it had that made it seem enticing:

• small reliance on potions
  
• status resist
  
• crit chance
  
• high attacks per second
  
• good % per second
  
• high mobility
  

After having committed to my Kaiser, however, I'm still unable to do most of the endgame content I might have been able to do, but I find myself irritated by Kaiser's drawbacks:

• does not have 100% stance
  
• needs si/inner ability/etc to attack speed cap
  
• poor mobbing
  
• awkwardness when trying to move and attack
  
• relies on wingbeat for good damage
  
• low damage per line
  

Are there any other classes that have most or all of the same benefits as Kaiser without some of those drawbacks?
