Cho Gath jungle is sleeper op
Cho top is strong but its hard to sway a game from top. In jungle however if you get rolling so did at least one other person. Chilling smite makes qs easy to hit and if someone holds onto a dash u can w then q if they dash you can catch up with the stolen move speed an q then w. Im able to do a full six camp clear before basing as chog'ath. Magus enchantment plus frozen heart is already 40 percent cdr toss in merc treads and with these three core items you can then chose between further dmg or tank.
Cons: this advice is coming from a bronzie ( tho i will be silver by Sunday night mark my words i finished the preseason in silver i can do it again) opening with magus enchantment does make you a little squishy and if you lose stacks your in a bad spot
p.s. my lolking ranked stats aren't necessarily as accurate as they could be because I've had 4 or 5 games where lag has hurt my ability to compete
