If youre going to pick divers and assassins and adcs like Lucian

Then that's fine. There's honestly no problem with that kind of composition.

But get the retarded idea out of your heads that 5v5ing a team is anything but complete lunacy.

You want to pick Akali mid? Go for it. But don't even bother following as a group. You WILL get kited, CCd, and instakilled.

Simple fact of the matter is that in this game, YOUR COMPOSITION FUCKING MATTERS. Barring being completely uber-fed, there is no way on earth you will ever beat a composition with a better 5v5 in an even game. You are literally handing the enemy team a won teamfight on a silver platter by taking away every strength of your own composition and engaging the opponent during/in theirs.

You don't have to be a battle-mastermind to understand such a base level of strategy.

For those who think I'm talking shit; look at my Warwick jungle game versus that composition example i gave before.

I was the one clearing both side waves for 10-20 minutes because the other 4 were sitting mid wasting valuable time, gold, and xp, trying to siege the other team while orianna sat on her keyboard and wavecleared, all the while being bitched at by those 4 for not grouping. Against my better judgement i caved in and joined them for a 5v5 in front of dragon.

We lost the fight horrendously, Vayne got a Quadra kill, then we lost 4 towers and mid inhib. We didnt come back from that.

You can be better than faker for all I care, I will not group with a team composition that is designed to split push.
