Definitely Naghan.
He can do a lot for the development of an individual project. There are many such people on every resource. But to do something for the development of the Heroes community as a whole — only a few are capable of that. Naghan is one of those people, and HeroesWorld is very lucky that he considers HeroesWorld his home resource. Among currently active Heroes players, I think only Vic can be placed in the same category as Naghan.
What did Naghan do over the past year?
Organizing the CIS Championship. Just for this alone, monuments could be erected to him in every city where the qualifiers took place. If it weren't for him, no one would have even had the idea for such an event. And even if they had, no one else could have organized people the way he did.
Organizing the inter-portal event. An event far less significant, but comparing it to local site tournaments doesn't even feel right. It's a pity that some people contributed to his departure from the organizing committee.
Looking at history, it was Naghan who started both the inter-portal events and the team and clan tournaments at HeroesWorld, which he also had a hand in back in 2009.
I don't know if my vote will be counted, but I have stated my opinion. I believe I have the right to do so.
