@rito games why is everything so broken

i was gonna write something about the devourer item being unbalanced but i just gave up, why is everything so unbalanced, there are too many items and champions that have unfair advantages like who at riot thought of giving yasuo infinite dashes, who thought of giving fizz a zhonias on an 8 sec cooldown and even less with cdr and just to make things better he can go through walls with it, who thought of giving riven more than one gap closer, why does brand have a 2 sec stun available at lvl 2, who thought of giving mordekaiser massive dmg and shield that makes him invulnerable to dmg, idk i just dont know im sad and unmotivated to play league anymore. ive been playing league since 2012 and now i get butterflies in my stomach right before a game because i feel like im going to lose once more because someone fucked up bot lane or sometimes i just assume its gg once i see the enemy comp and im almost always right. i surrender
