I wish "The Calamity" tree came with Ravenous Hunter as a preset instead of Relentless
Healing that is always present seems a lot better than out-of-combat MS when you're playing a Mage, especially when assassins all have mobility abilities and speed-boost items that make that 5/5 kill 48 MS look pathetic in comparison, especially since Relentless completely vanishes the moment you take or deal damage.
At least I'd be able to use the 2.5% healing to live a little and top myself off a bit whenever the assassins backed, and it would only get better as I got on the board, but Relentless just makes it so I can run back to lane somewhat faster all so I can get poked out/killed again.
