Hi I'm Addiction,
TLDR guides: Cho'Gall Patch
Questions: Twitter @addic03 or twitch.tv/addic03
enjoy.

T1: Great VS autos. Surge works well too.

T2: Seared synergises well with Fire(T3). Rollback for better ball position in teamfights.

T3: Fire if you went Seared @T2 or Surge if not.

T4: Good interrupt and low CD. Wombo at your own risk.

T5: Slightly more than the standard oh **** ability.

T6: Good for high ability damage teams. Surge otherwise.

T7: It's not much range but the slow is nice. TWoG would be good if it lasted 1 more second also requires too much coordination.

T1: Spurr for freer use of Z, Shadowflare if you don't think that's needed.

T2: Orb talents synergys well. Siphon for some more sustain.

T3: Takes some coordination to make the most of this but well worth.

T4: Stream of damage. Wombo at your own risk.

T5: Massive damage on the 3rd bounce is great for wave clear and tower poke.

T6: Makes your damage much harder to dodge in teamfights. Scorcher VS beefy teams.

T7: Shadowfury for melting fools in teamfights. If you are vs a team that focuses you hard getting Psychotic Break and ulting AFTER you die can be a viable option.
