Why does Riot keep tanky assassins good

Then explain why Tryndamere is good for the game

Rengar is not even close to "tanky" and "assassin". He is one or the other, never both.

Diana was like nonexistent for over a year after the nerfs. Runeglaive is the only reason shes popular again.

Rito likes them.

The thing is, they're pretty exploitable. Of course they have tons of damage because they are meant to do that, they're assassins, more so they're melee assassins so they have some built in defense. So they're pretty good damage wise with decent survivability. However they are extremely vulnerable to CC and damage. CC-ing these melee assassins is the best counter to them because they have little to none themselves and they just sit there soaking up damage they can't afford, a simple 1.5 second stun and they'll be decently chunked or completely dead with the help of your team.

Pretty exploitable, a simple click and stun can shut down a champion's main purpose.

Diana isn't too bad, Rengar is pure cancer though

Diana is not an Assassin, she is a Fighter. Stop calling Diana and Ahri Assassins, ffs.

Remember this: the tank meta was full of tanky burst champions, so yeah. Rengar and Diana are nothing compared to them.

Because the line between 'bruiser' and 'assassin' is still far too blurred in this game.

rengar sucks without kills, and diana... hell idk about her.

rengar can kill one target idk about diana
