Rift VU looks amazing, but one thing bothers me...
The spawn pool looks really plain on the PBE. In summoners rift currently, the spawn platform has glowing runes or something to show that there's some kind of magic going on there, so it sort of "feels right" that standing there is beneficial to you. In the new Rift, the spawn pools are just slabs of stone, which doesn't really indicate any kind of magical healing effect.
You've got all the little carvings and details in the stone there to put some kind of glowy magical look into them, but currently they just look sort of plain and it seems weird to me. Just sort of looks like the spawn pools are missing something.
This is my one complaint. Everything else looks absolutely gorgeous.
