Phoenix21so your proposal of practicing with a partner won't change the fact that he has better dm abilities than everyone who decided to sign up for the lower tier instead of the higher.
What I meant by people should practice, is that Timus isn't so much better than everyone else that there's no point in challenging. Could you honestly say Timus has the best dm in EU? I'm not sure you could, maybe though.
If people found a medic they could work well with, practicing to make their game seamless would give them a chance against the current best. I'm sure some prem combo could challenge them. Perhaps they just don't have time, idk.
