I'm gonna go ahead and call exaggeration and nonsense on Lakshmi ex only taking 5% of your health with her buffed tankbuster if you use TBN with rampart, for one TBN doesn't give you 'real' damage protection it just gives you a shield worth a certain amount, the only damage decrease there being the rampart in that case. Lakshmi's buffed tankbuster takes a little bit more than just 25% of your health if you only use rampart.
If it really was that good then Dark Knights would not be complaining about being unable to survive tankbusters from Lakshmi and Susano ex because they run out of mitigation to use while their TBN alone isn't enough to cut it
