The one thing Zeus would be good at is spamming spells, chain lightnings and shocking enemies.

The old passive, shocking everyone in range for a percentage of their current HP, would have worked brilliantly.

The arc lightning bounces twice at level 1 - laughable.

The lightning bolt is terribly expensive for a hero that's stupidly mana-hungry and has no means to deal damage outside active spells.

Zeus is bad and in dire need of a complete rework.
