Doesn't really mean much without specifics, but its good to see that they are making balancing tweaks

They sure are putting out a lot of balance patches... I mean, has the meta even been established yet?

Here are some things to balance the game...

Rosalina: When Luma dies, Luma wont be revived intill 20-25secs later, not 7-8secs.
Little Mac: 1HKO needs to be either nerfed or just takes twice as long as to charge up.


That is all.

Rosalina (a character i love btw) needs to be adjusted, her luma comes backwaaay to quick. She is getting closer to metakinght from brawl everyday.

25 seconds is an eternity in a standard 2-minute match. Get the job done in the 8 seconds you're given!

Yeah, but its kinda broken. Its starting to get pretty noticeable, and beside nobody does 2min matches :P

Yeah, as far as I've heard Rosalina is pretty OP if you use her right.

Maybe 10-12 seconds then. But 20 is way too long. Rosalina is much weaker without Luma, that 8-second window is supposed to be your opportunity to do some real damage. You probably know that better than me though.

Ok 15 secs :0 (we both nevr goin toagree on this :P)

Rosalina is definitely weaker but even without luma imo, she is on middle grounds of the roster. 

She only has one weakness. Her height and lightweight (she's actually in the top 10 lightest characters in the game) which definitely is a help to balance her out
