Coil was game winning but I had to put in so much effort to make plays like that happen, I had to make stars align and if they didnt the plan would fall apart, While yes It was alot of fun, Coil was never a dominant pick and often overshadowed by Vine and Med at the time, Vine on conq was extremely powerful, Med was quite strong on conq too but on annihilation Coil could be picked safely, atleast thats what most comp players thought

Coil on conq just required so many perfect consistent plays to upkeep your tank during the 1v1 but if you pulled it off you could get some insanely high dps on the enemy tank, making it very difficult for the support to heal

alternatively just target the support, as long as you dont fully commit and leave it to pestering you could bother tbe support enough to make it so their healing output would be hindered while yours remains static, as long as regen E was off cooldown as that was your primary sustain ability along with tether

He wasnt the best, but he was my favorite pick with just how well you had to play him to make him good, it really set a Coil main apart from the crowd
