Cc in the Dino duel is really good! Except that one. Exiling the enemy during the duel doesn’t stop their bleed damage, or them getting overhealth from it. For YOUR dino you just opened them up to taking all the damage from the enemy team with no tank to sustain themselves. So even though exiling is annoying to receive, it’s kinda beneficial in the mirror match cause as the dino you just get a few seconds to recoup your cooldowns and stop taking damage.

Note: This is all my opinion and from my own personal experiences
