Actually, I'll vouch for this whilst I'm here. Learn to space. Use Bombs/Sensors to force them to move in ways they don't want to. Don't hold forward on the stick and hold the fire button and expect to get the kill. Every death I've had against one, even those with laggy BS OHKOs, have all been due to me making some form of mistake.
Bucket did no wrong.
EDIT: Wow, 159 posts was the lowest on the Top 10 for the thread? Guess I'm safe for a while. XD
Splat gods have not been kind to me today. Yesterday i was 37-13. Today... 23-27. Splatoon is really like a wave. You rise up to an apex. Then come crashing down for a while only to rise up again etc etc...
