No 2 player Arena mode

[Buckley76]

Please make three players the minimum number for Arena mode. In two player, there is no option but to tie. So, all it does is reduce ELO for the higher ranked player and add ELO for the lower ranked player. So far, it hasn't allowed any movement in arena points, but that may be because of the lack of significant difference in everyone's arena standing. Regardless, it makes no sense to have two player arena mode.
