Is it difficult to get a quadra-kill with a tanky champion?
Cuz i did, with a tanky garen, which probably isn't saying much, but still, team fight and i get a quadra without ever going under 50% health. (vanye stole the penta lol). I wasn't exactly fed as much as my laner got bullied out by my spin-to-win(altho he was ranged?) and i just farmed a bunch of cs. Flawless game too( now im just fucking bragging) but still, best game i've played yet.
Edit: I do realize that garen is a noob-friendly champ.


is an example, since he is 100% single target burst damage.
do decent amounts of damage so it is easier for them to kill their enemies. In your case for Garen, I'm guessing it was more or less your teammates getting them low and you lawnmowered over them.
