Ability Maxing Order

So I recently got informed that maxing E is the new thing and I've been doing it for a while now and it's certainly not bad. Firstly I wanna know if it's still regarded as the most optimal path for full enchanter builds, and secondly, I've been wondering if maxing W seconds would be terrible. Because maxing E first already leaves my Q feel weak for a long time and from mid to late game I'm not casting RQ's too frequently anyways, so I just ultimately get the idea that with this build Q is the least important spell and most of it's function really is just to have an occasional slow and more importantly proc passive, while the W root time could be good to get maxed out faster. Thoughts?
