Dood, believe me, I have the same question lol! I actually play her too aggressively sometimes and don’t use Luma enough (Mood pointed this out when we played, thus I’ve been working Luma in more lately).
Even stranger is in the full match, D3 KO’d me first at *65%. *I literally had to play hit and run to avoid losing.
Rosalina is one of those characters that can do no right now, all because of a few sets all the way back at APEX 2015 (which to me were entertaining but you know, I;m weird, I like footsies and zoning and stuff).
