So how many specs can actually solo Zekvir?

The entire fight on tier 2 is dependent on Bran. Even the guys who have done it have said so themselves. You have to be insanely lucky with which Bran you get. The closest I’ve gotten to beating Zekvir Tier 2 was 10%. Bran just did not engage the last cocoon that was hatching even though he was standing 10 feet away.
