I just unlocked it and plan on saving it on my new scrapper. Next time I see you chatting on Radio Virtue I'll send a tell so you can smack Anti down.
For what it's worth, the new Anti-Matter arc is a million times easier than the old one. All those "Kill Alls" were replaced by "Defeat bosses" and "Hit Clickies". I dreaded getting the arc on my Scrapper but had it done start to finish within an hour or maybe a touch over.
Anyone on virtue have the mission for anti-matter, think he's the only AV I still need for the arc. If so I'd love to help you kill him
