Dooku can do the same at the beginning of a match. Paired with Phasma and an assist caller, I fought Dooku tonight and he had 12 attacks in the time it took my entire team to take it's first round. Sorry that OP had a rough fight against Fives, but I agree that it means a strategy change is needed on his part. That is all anyone ever says to complaints about Dooku, so live and learn.
