Suggested Changes to the new Catalyst

The main problem with the new is it's regen is WAAAY worse than the current one during lane, it only had the potential to reach the same numbers or be worthy late game if you are playing a tanky mage, which conflicts to the fact is an item you need to rush. So you are kinda forced to buy the item in the moment of the game it's worse.

Also, in the scenarios in which you could get enough damage done to you to get bursts of mana, you won't get enough time to spend it, and as the HP you can get from mana spent has a top of 15 hp per cast, even if you could expend mana that fast, it would give negligible hp, so not even good on tanks.

Possibilities:

1. Make cheaper
2. Increase the max HP you can get with your level (max 30-60 hp per cast depending on level). Considering that that only way to reach the limit is casting spells that costs hundreds of mana, there are probably not more than a couple champions that would reach it, and if they do is by wasting a lot of mana and by building up to it forehand (probably only and )
