Linas is a shameless Storm spammer – he is one of the top 100 ranked Storm players according to Dotabuff.
His videos focus on the mid lane, mostly told through Storm's perspective, but applicable to most mid heroes. In his channel, you can also find guides on other heroes, coaching sessions, and various other topics related to improving one's gameplay.
He has a small channel, but his content is very high quality – very well written and edited, and he deserves to receive the opportunity to develop and grow it!
