Good day. First of all, I want to express my sincere gratitude to you for your work! And I would like to ask, what is the estimated timeframe for completing the work on the global changes to the map? And how playable is that duel mod in the regular scenario mode, rather than in duel mode?
The next format is the arena, in which heroes will be leveled up, equipped with artifacts, and assembled into troops. Balancing it may take 6-18 months.
The final stage (the map) may take another year or two.
So, the map will not appear before 2016, I think.
Regarding the playability on the map now, in general, you can play without balancing. However, scripts and features related to them may not work.
For now, I would recommend the duel format, as it is already done and tested. And everything on the map may change significantly in the end.
