Mace Windu not interacting with JMK correctly?

So essentially how it Mace Windus kit reads is when Mace gains taunt he dispels it and gains 2 stacks of resilient defense instead, and with the JMK lead Galactic Republic tanks perpetually gain taunt if they have protection and didn’t have taunt. 
So, I feel this should mean Mace SHOULD have a max stack of 8 resilient defense and always be taunting with protection like General Kenobi since he is converting those taunts given by JMK. This is not how it works in game though… in game he gains the 2 stacks of resilient defense at the start of battle and that’s it. He won’t gain anymore stacks unless it’s through his own kit.

Only reason I bring this up is because it feels like Mace Was designed for a JMK team with his high health, turn meter swap, and the mentioned reaction with resilient defense the way it reads. But, he is hardly used in a JMK team simply because General Kenobi can perpetually taunt and Mace cannot even though the kits read like he should.
