Spoilers: You won't be unleashing the Kraken as much.
A major update for Splatoon is coming early next week, and it's bringing a whole host of balance changes.
The listed changes (PDF link) cover multiple weapon buffs and debuffs such as rollers needing to hit dead center for a one-hit splat, walk speed increases for the N-Zap line and adding additional Rainmaker shield damage to the Slosher line. Sub and Special weapons have come in for a nerf, most notably the Kraken.
Changes have also been made for balanced in Ranked battles, and the calculation of points for S and S+ ranks will be changed as well. The patch will launch Tuesday evening in North America and Wednesday in the rest of the world at standard update times. The notes do not mention if this patch will enable playable Octolings, but that may fall under the "improvements to the game experience" disclaimer.
The next Splatoon weapon has also been announced for tomorrow night; The Rapid Blaster Pro is a variant that comes with increased range, sacrificing a bit of damage, and comes with Seekers and the Inkzooka.
