Discord is where a lot of clique-think meets reality, and the result is a mess. Not a surprise. 

RP wise...it's just more functionality than Tinychat and Skype. It's easier for people to come and go from Discord servers, and you can easily hype up your friends on one server and then bring that to another server. It's almost like digital tribal warfare at times when the drama really kicks up. 

It's pretty funny, and sad. 

Yeah I can see Discord increasing the level of toxic drama, just as much as it increases convenience and functionality for GMs and RPers. Staff often finds it's a very small percentage of people that participate in the toxic drama and RP regularly. You're usually around for one, or the other, rarely both. Discord exposes people that way.

Balances out in the end.
