@Riot when you rework Tryndamere and Aatrox fix how their steroids work
Both of them only get a steroid from being in a fight longer or from being low hp(Tryndamere).
The game is so bursty that they are lucky to last 2 seconds in a fight outside of Tryndameres bullshit current ult or Aatrox passive.
They need to have more reliable steroids/moments of power similar to these melee champions

What is the similarity between those champs?
Fiora can press R to be able to have a moment of power and fight.
Irelia can press W to reliably do bonus damage on her autos.
Olaf can press W and R to get bonus AD and attack speed.
Yasuo has double crit and gets bonus armor pen with his ult.
Yi can get a reliable attack speed steroid and true damage on all of his autos.
Tryndamere needs to have been in combat a while to get crit and Aatrox needs to hurt himself a while to get attack speed.
