Chen by Thinhead

Level 1

Level 1

More consistency between choices. Pick your quest.

Level 4

Pick your survivability/mobility. Small buff to Elusive Brawler cooldown reduction so it doesn't feel quite as bad. Moving while drinking should be able to mitigate some of Chen's familiar problems relating to being stuck in place.

Level 7

Brewmaster's Balance was always overpowered.
Keg Toss looks a little pale but good synergy with other talents should make it a strong pick.

Level 10

I think both Chen's Heroics are fine.

Level 13

For the price of needing to combo W->Q instead of Q->W, Pressure Point would feel good if it was a stun.
Moderate buff to the Shield amount for Enough to Share. Good synergy with Drinkin' Stagger.
Added AOE buff to Ring of Fire to compensate for putting at at level 13 instead of level 4. Good synergy with Keg Toss.

Level 16

I was going to put Deadly Strike here with a smaller (10) Armor debuff but felt like piling too many effects into one talent so I put it at level 7 in its original form instead. Chen burst was already pretty good for a warrior so I would watch Exploding Stomach Kick closely.
On the other hand I think the other options here are also pretty compelling.

Level 20

Stormstout Secret Recipe is pretty bad in its current incarnation. I still don't think 1.5% Health per second is real strong for level 20 but it could be a compelling option for a defensive/heal deficient setup.
Drinkin' Brawler should enable a more aggressive playstyle by allowing Chen to "drink" at a slightly reduced rate with his auto attacks. Great synergy with Elusive Brawler.
Heroic upgrades unchanged.
