No fight in BFD requires addons or voice chat at all. Even if they did, how do either of those things make a fight “retail-esque”?
I’m not going to bother getting into a huge argument about it. It’s just clear that the devs who designed this fight worked on retail. It’s like you can’t define art but you know it when you see it sort of thing 
Sounds like a cop-out answer to me. As someone who has played retail, nothing about anything in BFD screams “this is a retail fight” to me
Are they “retail fights” because they have actual mechanics that involve proper interaction and resolution, instead of “stand and hit and have enough health/defense to not die”? Because if so then bring on more retail fights. Tank and spanks are the most boring form of content to ever exist
You need interrupts and to coordinate sleeps, which isnt that much to ask.
The healing of p2 is a prep check. There isnt actually that much going on there if people brought faps and shadow protections
At the end of the day, not everyone needs to clear everything. Shrug.
