Wow, this is really great, thanks!
EDIT: Regarding Earthshaker
Another trick is to shift-queue your enchant totem and fissure after you blink in and echo slam. Earthshaker will finish his 0.5 second casting backswing after every spell, meaning your stuns dont overlap as much. It's not as efficient as perfectly timing the stun sequence, but you'll get more stun time than just spamming spells and it's easy to do for new ES players (who seem to be the target audience for your site).
Another tip is that, if you know a fight is coming, you should enchant your totem beforehand. The duration lasts longer than the cooldown, allowing you to get two boosted autoattacks off back to back, similar to setting up overpower before a fight as Ursa.
Oh one more thing, I believe you can use echoslam to kill couriers, but I've never done it myself.
