So this rework was done during the Meteor Hammer OD times, but I've refined it a bit since. The biggest changes are that mana steal is more of a central aspect of the hero again, this time through Essence Flux's second passive effect, and Astral now has counterplay that the enemy can do, releasing the banished hero early. Of course, since Astral has 2 charges, OD can then counter the counterplay right back, at the cost of both charges.

Another big change is that his ult, which has been known as an all or nothing type skill, now has some counterplay with the very long cast time and visible radius. But once again, OD can counter this by imprisoning himself to make himself safer from interruptions.

The last big changes were to Arcane Orb and Essence Flux. Now they're consistent in that Orb now works off of max mana rather than constantly changing current mana, and Essence Flux has no proc chance anymore.
