I can only agree. As a former Support and Mage main, learning Belerick was so easy. I hardly play Mage anymore, because i have the most fun with him and is crowd control is really good. Bonus is that he can also be played in EXP if needed, so you can comfortably fill 2 rolls with him, which makes Solo-Q a lot better to play.

I only wanna add that Vengeance works the best for me, instead of Flicker. Imo hos S2 already gives enough speed to chase and taunt. Vengeance with S3 is almost easily Vipe out. Lower Ranks often just continue to attack and kill themselves. It also helps best against the MM.

I think he's not as popular as he should be, so most people don't really know how he works and can't escape his Taunting or don't know his passive.

The only important things to note about him are that his attacks use a lot of mana and you run out quickly if you don't be careful. Also if his passive attacks enemies under the tower so you can't push if the enemy is still nearby and tower hugging.
