Continuing the discussion from Heroes of the Storm Tier List:
It seems like Chen Stormstout might be a little misunderstood. And after hearing comments on Mumble last night it’s not just Vocino that wants him to die in a fire. So while it’s free Chen week let’s take a moment to evaluate this hero.
Chen is about cooldowns and area-of-effect. The cooldowns on his abilities are all 5 seconds. Essentially you want to initiate with Q, then target W so that you slow as many targets around you, then ignite them with E (bonus if they are affected by W).
Once you’ve dropped that initial burst (60 of your 100 total brew) you still have enough brew to perform Q-E again, or you can press D to start channeling your brew back while also shielding you. This will protect from the enemy attack while your team moves in to handle things.
Chen gets useful talents such as Swift Reflexes (dodge) or Amplified Healing to keep him alive while chugging, and Ring of Fire creates a fire aura for a few seconds after you use E.
Let’s give Chen a chance!
I’ve also found a guide/gameplay video of Chen to help educate.
