Spells: Root landing consistently with 255 (300+ MR)

[Flexin]

I could be incorrect on how mechanics work, but should a bard with 255 mr (significantly higher realistically) be commonly rooted by green mobs.

The main culprits are NPC pets, specifically in wakening lands and plane of fear, many of which are mid 30's and green con to a 60 bard.

As I mentioned I could be mistaken and this could just be how the game works, I understand everything has a small chance to land but it's about 40% when cast from pets.
