The end of the arena season is delayed for an indefinite period. There is a variety of reasons but the main one is that bugusers found three new bugs and one of them is increadibly critical for the fair end of the arena season. At the moment, we are working on fixes, but even after them it will require time for the fair players to gain rate and so on.
Indefinite period - is not euphemism for the phrase "we don't care, wait for a few months", we just don't want to set a concrete date and then delay it for some other reason. We will make sure that everything is ok and then set a date.
