It's clear that having an online tournament is always better than not having one, even if it's just one game a day.
The problem lies elsewhere – organizing a CIS tournament on HotA leads to six months of forum arguments (protests, streams of negativity) before and after. Personally, this process doesn't scare me, and I even find it somewhat amusing, but for the development of Heroes, it's more of an undesirable phenomenon.
Therefore, I would prefer that club tournaments for SoD and HotA are held separately, so as not to create unnecessary competition.
The Minsk option, by the way, is interesting, as there are many Poles in the HotA community, so a good contingent might come from them (although it's better to ask Jelen117 about this).
A visa is required to enter Belarus, so it's unlikely that anyone other than me will come. With Ukraine or Moldova, it's a different story.
