well I am honored that you used my idea for the burrow, although if you felt the movement speed was too high, you could say, reduce by 10% per rank and have her ignore terrain and unit collision (she is underneath all of it after all) and yeah the passive seems like it makes a lot more sense if it starts stacking after the ability comes off of cooldown
