Thank you for the feedback! You're right, I may have gone a bit overboard on the BT changes, even if the intent was to compensate for the reduced base life steal.

I'm also sad about removing ER's mana restoration, but I feel there's also a deeper issue here of mana being extremely difficult, if not impossible, to be satisfactory on its own on any champion when there are so many items that unlock its gates. If a champion's mana gates are "just right" then the existence of mana items for them just devalues their mana gates, and if they're balanced around those items, then they end up having mana issues on their own. This might be going a bit too far, but I think itemization may ultimately have to drop mana and mana regen completely in favor of improving mana on everyone.
