Even as an English speaker, caster Jun is an absolute powerhouse.
I love Captain Flowers, and Atlus in the LCK is amazing. Monte is a classic, and well, I could list a ton of casters but I would say that basically every caster LoL pro has are insane but would love to hear your caster GOAT
I don’t really watch much anymore, but back in the day when I watched LCS every weekend my favorite by far was Rivington.
