At this point, I recomend getting Annie if you want to play mid and Yi if you want to jungle. Then simply save up for the cheapest assassins for each role. Akali, LeBlanc, or Katarina for mid. Evelynn for the jungle.

Garen is good and easy to use for top.

Master Yi is for Jungle.

Ashe for bottom lane.

Leona, Soraka and Sona for support.

Annie for midlane.

Singed and Sivir for coop bot farming (if any ever needed).

Ah how I miss influence points

Is there a good way to farm essence?

Annie is pretty easy and super powerful, I think I'd recommend Annie ^^

Get first win of the day on some hard push champ (Yorick, Tryndamere, Heimerdinger, etc.) on Twisted Treeline Coop vs. AI then play a ton of ARAM.

Thanks!!

Master yi is a assasin champion worth 450 BE and it is also a jungler/farmer.

He's not a true assassin due to his DPS and relatively poor ability to escape versus keep fighting but he's not that far from being one either.

There are not preety much good 450 champs save 3150 and main akali just watch professor akali when you start. Akalk needs just 3 kills and if u are more than lvl 5 mastery u won the game just gank bot and farm thats all
