Is Ivern Taken From this Concept?

Okay, so I love Ivern. He's amazing. But his kit seems very familiar.

Similarities:

• Creates brush (gains bonuses from being in brush)
• Seed on ally (sapling on enemy)
• Summons a shambler

Let's face it- Long Legs Larry is a borrowed concept. Still love him though.
