Either.
Make Snare a counterplay to Expedition.
It can have a Major (30%) and Minor (8-15%).
Or
Make Expedition a True Counterplay to Snare by adding Snare immunity to Expedition skills
A Snare is only to gain ground on a fleeing target or to assist in keeping an engaged enemy in proximity to your AOE (Hurricane, Northern storm)
A Snare should not be an Immobilize, but with 60-80% snares it practically is an immobilize, so currently you can get jumped by someone, ((get immobilized)), break free, get a skill off and try to engage, ((get stunned)), break free, ((80% snare)), have moved 1/2 a Meter in 6 seconds. It does not "Feel Good" or feel like combat and counterplay.
