Anarchy is in the name, of course there is some disorganization with the absense of a hiarchy and a central government.
But for me, my main feuds have been in NGW, IWT and RWK...
Danger Zone vs Extremely Lethal.
A mini-feud with bloodlusT that didn't get far.
Ivy Hale vs Reagan Cole
Ivy vs Spawn both only lasted a month.
An implied dislike between Ivy and Tyson Storm
Ryan Vendetta's narative with his trainer and some of his past.
Ivy joining in the feud with Jack Rogue and Jordan Bull
Vendetta vs Odin Anaxagaros which overlaps with...
Vendetta vs Tyler Keenan.
Only long feuds I have had was DZ vs El which is linked to Vendetta vs TK. Most other feuds last a month or two max.
