"Twitch is an assassin and marksman hybrid, it's normal for him to delete you"

Ok, but how is it okay for him to go into stealth, appear outta nowhere, stand at a safe range AND delete the enemy team instantly? Normal assassins like Zed, Rengar, Talon, etc all require to get on their target and land their abilities. Twitch appears from nowhere, presses R and deletes not only the enemy squishy, but the entire team.

In a teamfight, someone like Zed can only go in and attempt to kill the enemy ADC, then he has to retreat because he has no abilities left to use. But with Twitch, he doesn't have to back out because one second after he appears, the enemy team is dead anyway.

Soooo, yeah. Fuck Twitch.
