Proof of Concept for 5xF4 seems nice and all, but in practice this means:
- Mandatory use of Swiftcast
- no Thunder, ergo no Thundercloud procs for movement
- Third rotation will fall short due to Swiftcast-refreshed Enochian

All in all an even tighter rotation than there is now due to Enochian timer, which is bad in every case where you have to move. Having no Thunder is worse than the extra F4 since full-ticked Thundercloud procs are stronger than F4.
