there is not real schedule. The only one close to be known it is the 4k around the 17 of every month. The rest change as surprise said by CEO when took over. Now, I have my doubt the quad will be next because we got it early this month. Maybe overload preventor cooling/regen unit. If not the cooling/regen then maybe will be the PHYS Shield Platinum Fortress the yellow one.
I do have the schedule that's kind of only accessible for certain members, but I'll screenshot it and pm you of you want.
And about the pattern, the 3k offer has AT LEAST 2 QCB 3k offers in one year, and AT LEAST 2 OP 3k offers in one year. The others could be just random premiums or legendary versions of OP or QCB.
is there a pattern on the offer dates like every x weeks? I'd really like it not to be QCB yet (with my calculations, can only reach like 1.8k by then T-T)
