All we know, that Blackrock is not blizzlike realm. That is fun realm, where players can buy gear for honor/arena points. So 1 gear part (trinket or ring, for example) costs 62000 honor points with honor limit 75000.
Imagine situation: i rushed 1.8 with my 2s mate in start gear. I need a lot of honor for gear: neck (39k), back (31k), wrist (31k), waist (31k), feet (31k), two rings (64k + 64k), trinkets (64k + 64k). I need a lot of time to farm all of this, so i HAVE TO stop play arenas and start farm honor. With honor limit 750 000 (like wow circle did) i can chill farm honor when my mate is offline and at the right moment i can buy all of this gear parts simultaneously . I dont see any problems/stoppers to dont realize it, because Blackrock is not blizzlike realm. I guess blackrock players will support my suggestion.
