After rewatching the videos I think there are a couple games that I would've undoubtedly won if I had healed better. Last game on video one I think--I got the Warlock down and my team was basically at full. Then I lost a 5v4 in my favor.

Considerations:

1. I'm thinking a Deathgrip/Chains of Ice macro is necessary. Two games the initial target got away because I was depending on Hammer of Justice to keep them stuck before I mashed my Chains of Ice button.

2. I need a better healing solution. Period. DS/DS and healing need to be second nature.

3. I completely forgot to use Hand of Protection on my DK in any game.

Overall I'd say that I need to get more comfortable with my keybinds.
