I created this build mostly because I love DoT characters and I used to main an Affliction Warlock in WoW. Morgana is kind of like that in a way, but especially in this build.

The reason behind W max first is because it's makes farming really easy in the mid lane and it makes her more into a duelist in the support role. This build can do some really nice damage and is really great for helping your jungler with dragon, elder, etc due to W refreshing it's own cooldown. It's also really annoying for teams that want to push/shove because you can clear the wave in like 2 seconds.

Her Q snare is already really good at level one and glacial augment double downs on that.
