"[Mini Gnar] The reason to go Q as a max is because of the slow is a very clear upper-hand for Gnar player, with his movement speed of hype combined it makes a great combo to use for maintain you'r enemies at distance and at the same time give a big damage output both early and late game.

[Mega Gnar] The Q aswell here is a usefull advantage to the mega gnar, as for his slow speed the Q makes up for it, as the boulder tossed deals alot of damage and provides him to get closer to use his W to stunn makes him inescapable.

With the E wich ultimately is ur way out / or in a fight. Is good to keep it at one so you always have the escape or initiate alternative up in early game, and to become a harder target."

Onto late game you will have to make up for mini gnar and mega gnar in a way wich benefits both of them. Either way you can go all tanky, or you can become the shredder. This is the way that for me myself worked the best. I strongly recommend this gameplay for aggressive gnar.

But keep in mind, Be ready for when the timer makes the beast unleash, and be ready when it disappears, it can be hard for some to maintain the balance. If you dont want to turn try to be calm at 94% rage and wait for it to drop so you can keep the farm up, and in fights keep it at 96% so you'r ready for anything.

I hope that this information and guide will provide you an alternative good way to play Gnar, wishes you all the luck on the field of battle!
