Well this sucks we have to do double the arena score for these extra t1a’s in t1a arena. Instead of just putting them in the already established milestones now we have to spend even more time in this arena, I’m going to assume the same applies to the other special arenas like t4b arena. I would suggest going back to the already known milestones because we don’t want to spend tons of time on these arenas, should be quick and easy to complete.
