Hero giant rework ideas

It's clear to everybody that hero giant is significantly worse than all the other heroes (or champions for what matters), so here's some thoughts I had on how to make it better.

1. The ability also does area damage and knock back on all the circle area (like evo rg)

2. The troop that is launched on the other side of the arena also gets some sort of malus. I mean, sometimes using the ability creates another problem you have to deal with on the other side of the map, sometimes leading you to actually lose the game. Maybe the troop could lose half of his health, or become more vulnerable to attacks or deal less damage.

3. A complete rework, something absolutely different.

II like they made giant hero, but it's obviously not a good card. His ability is too niche, sometimes using it even cost you the game
