So, people claiming it's fine that TBN can't mitigate fluff. Can you tell me what exactly makes TBN good then?

It's not really any stronger than the other tanks mitigation tools on tank busters (120k damage tank buster would be mitigated about 24k by sheltron while TBN gives about 29k shield). It has a shorter recast, but what good is that when you can't actually use it in that time?

You can say it's not a problem that TBN is less readily available than the other tanks mitigation, but why should it not be as readily available when it offers no decent advantages for it?
