If you're going to mention cold-blooded, you could at least reccomend swim speed up (which makes it better for ambushes and flanks what the .52 is best at). I'm even planning to ditch ink recov up for swim speed in light of this. I'm lower rank, (A+ as of writing this), but I know what I'm talking about. I just feel it's too important not to mention for this. Also, ink saver sub doesn't do much and is unimportant, as you're worried about recovering after a wall vs using less ink from it.
