Experience? Are they viable or do they eventually fizzle out. Thanks
They’re just as viable/likely to stay or eventually fizzle out as any other alliance. Some will fade away, some will survive.
I used to be in a pvp alliance. Not a top tier one, mind you, our pts threshold was ~600pts. Took a year long hiatus. They were still there when I returned, so I joined back up. 
I’m in a pvp focused alliance and I’ve been with them for 5 or 6 years now. There are plenty of other pvp alliances that have been around for a long time now.
Are there really any PvP only alliance out there though?
By this I mean are there really any alliances that won’t let you play other aspects of the game. 8^)
Thanks all
