Well written article on how Azubu's success might mean the rise (and dominance) of Korean teams in LoL, and how they will blast the meta.
The real principle behind Azubu is creating a low economy game. This has many similarities to the early metagame in Starcraft2, when Korean players would use incredibly aggressive openings such as one-base 9pool or proxy-2-gate to force low economy situations. By forcing aggression, Azubu takes the emphasis off last hitting minions and forces teams to respond to them. Many EU and NA teams are not comfortable with playing in these scenarios. Once Azubu seizes the initiative they then try to create an early game lead and ride that to victory. Often this lead will take the form of an early tower. Indeed, in these low economy games we often saw both teams sporting very low cs scores at 20 minutes for a professional game. However, by taking towers and champion kills, Azubu finds an alternative source of income that both gives them a gold advantage as well as helping them dictate tempo.
