Is anyone else noticing that Arcane Torrent refunds only 6000 mana at 90? I don't see anything else. It didn't feel weak before 90, so maybe it's bugged for just level 90? It's not just an error with scrolling text; I'm watching my mana itself increase by only 6000 when I have 300,000. Did I miss a nerf to Arcane Torrent or is this a new bug?
