Player rating for tournaments across all installments of Heroes.

No, in the Big Spear, not the Helmet, there is one rating — THE BIG SPEAR TOURNAMENTS RATING! Why divide it into five???

:) Now I understand even less — what spears and helmets :)
We have heroes 1,2,3,4,5. If a player plays all five versions, a rating is calculated for each of the 5 versions, and he has 5 ratings. + 1 universal. If he also plays online, then another 5 ratings + 1 universal. That's already 12. At the moment there is no online rating. Fine — 6 left. Well, let's discard the universal one. 5 left. They are calculated by three systems. 5x3=15. AlexPank is about to whip up another system = 20. Is that not enough for you? :) And as for spears and helmets, I have no clue at all :)
