I played literally a single Gwen game at some point, didn’t really enjoy it, but I learned that the thing under her health bar is her stacking her Q with auto attacks which makes her do more Q’s and it times out if she isn’t attacking anything.
Ever since, laning against her has become a lot simpler. I’m too lazy to do it, but I’m sure if I just played a single game of every champ I’d have similar revelations and rise up the ranks.
they just kinda randomly added it in 1 patch and that was it. 0 effort after that to really ever point it out to anyone so you just kinda have to know it now.
