Champ Revamp - Groot
I think Groot could be a really fun character will a few really easy buffs.
Special 1
Add Bleed - A good bleed like Hawkeye. Also when his signature ability has generated buffs make the bleed lacerate causing double the damage.
Special 2
Change the special to a difficult ranged attack. Perhaps a throws his arm at you like a spear that attacks 2 or 3 times but can hit you from any position on the screen. This attack should also cause intense bleed, But evadable with skill, like hulk buster.
Special 3
This one is ok , but it should instantly set off his signature ability, and rocket should provide him with a unique buff that stays for the reminder of the fight. This ability would be added to the signature ability and Groot would have to be awakened to utilize. Also unique buffs would be stackable
Buffs could include
Increased Bleed - 50%
Increase Regen - 50%
Double All Buffs
He also should be immune to electric attacks.
As for regen:
Hold block for 1.5 seconds to trigger regen. A cool down timer can trigger of 6 seconds. When the Rocket buff is active regen can increase and be stacked.
Heavy attack
It would be neat to have a projectile spear thrown. Unblockable, that triggers a 100% bleed if struck. With a chance to cause a open wound that would weaken an opponent. In this weakened state the opponents power is drained, and the opponents attacks have a percentage to miss.
Friendly nature:
This has a ok mechanic. Also add the ability to manually trigger it. Dash back and hold block for 3 secs. The icon should be a different color that the regen.
This would turn Groot in to a true bad ass offensively and defensively.
