Her fall speed was better off where it was. I will stand by this until I play a good Samus or see really good footage. And she was always heavy, she just falls faster. Literally the only good thing I've found about her new fall speed is her ability to survive stuff like Fox usmash at higher percents - her jumping wasn't compensated, or else not compensated enough [ledge-drop -> jump -> missile -> regrab ledge is no longer a thing] (her bomb jump was compensated, I can see that) and she feels much less safe to recover with (definitely easier to gimp, both recovering with her and playing against her).
Her old fallspeed was just fine - anyone who said her combos were bad before never played my 3.3 Samus - I zero-death's a few people with her, one time not even ending with a charge shot (though she was reliant on charge-shot to get real zero-deaths - I don't know if that's changed in the new one, because I can't play her properly and miss her old form way too much).
This is also literally the only time I've ever been THIS upset with a change, ever.
I don't need 2.x.6. I don't even necessarily need 3.3 with her dtilt and uthrow buffs - heck, I'd take 2% per dtilt and only 18% while still self-damaging 10% on uthrow if I got her old fallspeed back. Everything that was fun about playing Samus, especially in contrast and compared to my other characters (Falco for sure, to a lesser extent, Link, MK, and some others) is just gone for me.
If it's not ever going to be changed back, ok, just tell me so I can stop dreaming I might enjoy playing Samus again, and I'll just play a lot more Melee or P:M so I can enjoy her there (or vBrawl, as bad as she is there).
