She was good in exactly 1 meta, and only in the top ranks. Dive. Outside of that she has always been mediocre to bad. Was solid in seasons 1-2, but then again pretty much everything was as ppl were figuring the game out, wasnt much of a meta other than play ana and reaper in part of season 2. 3-4 was mainly triple tank, wasnt played in that. 5-9 was dive, she was amazing there at the top, not great at most ranks. Since then has been pretty damn bad. Wasnt good in double sniper, hasnt been good ever since brig was added, armor, burst heal, denying space etc hurts her tons. Wasnt good in goats, isnt good in the orisa ladder we are getting now.
So yea, it isnt that she is bad in this meta, and good in any other one, its that she was good in only 1 meta, with the caveat of being in high ranks.
