Anyone notice how in the fight in the last quest of the Ninja Job series, the opponent uses a "lost 4th Mudra"... That a possible hint about the next Ninja Job skill?

If so, we're already struggling to squeeze 3 Mudras + Ninjutsu into a 2s gcd, how are we ever going to manage 4 + Ninjutsu?

As well as 1 new 2 step combo, 1 new 3 step combo, and 4 new 4 step combos.
