I gather that exact calculations behind Iron Gauntlet Score have not been published yet. However, some possibilities disturb me greatly. First of all, is it informative score only without influencing anything else (especially MM)?
If it does influence matchmaking, then in some cases unlocking cards’ levels/trait/ascensions may not be beneficial at all (or even harmful while playing PvP).
I am unable to find detailed information regarding new MM. Does one’s rank matter on the ladder matter? Does player’s level matter (it used to before)? Does defense teams’ iron gauntlet score matter? What else does influence matchmaker?
I believe game’s rules should be transparent in this regard.
