Just don't vanguard when you don't host. Geth Infi ftw.
Great advice, unless you want a Novaguard and Smashguard in the same match. Or slayer. Or more than 1 Vanguard of any type really. And as Fury points out, it isn't just Vanguards, they're just affected the most.
Though after the cooldown nerf on smash, not really sure why you'd both with Smashguard over a Phoenix adept now anyway.
Anyway, of all the bugs in this game (and there are many) the two I want to see addressed the most are the constant lost connections in the store, and the vanguard glitch because they are the most game-breakingly annoying.
They can follow-up by addressing the Geth Rocket Hacker and their "I'm going to fire three missiles at you simultaneously through this wall" bull****, the stun-proof Geth Hunter, Banshee magnet grabs from halfway across the map, Phantoms running you through with the sword despite theoretically being staggered, and maybe even fix ULM on SMGs so you can actually carry them as a secondary weapon.
