Celtic Heroes

I'm currently lv80 atm with full warden and I'm wondering when I shud get astral armour and a rouge price of each part also I know its not related to the topic but does anyone have a rough date or bit of a month that update 4 will come as I'm looking into improving a lot by then for new drops and items and actually getting into battles

I got mine for free so I really dunno. But I say least try to get them from boss drops. Also ranger and warriors are different, ranger's spaces are 20k and the minds are 30k I believe. The earth rocks are like 500gold each in my opinion.
