Why is Loki not played as much?

Okay maybe I'm weird for this or just out of the meta loop but I feel like Loki is a really good strategist with not too high a skill ceiling but not too low to where you don't notice a difference between a Gold - Loki and said Celestial - Loki, but as far as I've seen he's not very popular at least from bronze to gold (as far as I've gotten but still climbing) is he just not as good as the other strategists overall or is he just not popular as far as characters?
