Cho - As Cho, a lot of what you do is going to be based on how good your Gall is. The Gall is where most of the damage is going to come from. You hit hard too of course but a good Gall will always out damage you and most of the team. IMO Gall should build towards tanky/sustain and let Gall focus on dmg in most games.

If you guys have good teamwork and a solid team, going CC Gall is beastly. So many slows and body blocking so your team can deal the ultimate damage. But your team has to be with you harassing them so they won't turn around and blow you up.

If you don't intend to build him tanky i like getting Rollback at Tier 2 so i can harass more from distance.
