Smash Master
Life pretty much said the other stuff, so I'll cover what he didnt.
A quick comparison of KB between Squirtle's downsmash and several other downsmashes that behave very much like it. We received feedback that Squirtle's 3.6B KB was uncommonly bad at low percent, and on investigating it became apparent this was true. The changes bring Squirtle's downsmash in line with others, while maintaining what the original 3.6B change accomplished in increasing its KB curve.
3.6B's Dsmash was weak yes, but there was no reason to reduce the base even further and jack up the growth so much. It actually wasnt even that bad, 3.6B dsmash would hard knockdown Fox at 30%ish (Everyone's real problem was that Fox could asdi down and shine Squirtle between the second and 3rd hits of dsmash if you snagged him out of the air with it)
This change removes a ton of squirtle's followups on almost everyone but heavies past 90% with dsmash, if not out removing all followup ability if they just di up. You can BARELY uair mario now. If you guys wanted to make Dsmash better at lower percents you should have just bumped up the KBG from 80 ten or twenty points, and left the base as is.
