7 Accounts is just the beginning for some of these players, Some of them when go up to 15-20 accounts. If you played Pre Open Beta you would know that Auto Pots were available in the Cash Shop and Token Shop for a good few months and even at the last days of POB when everything was going super cheap Auto pots were still expensive 50-100kk. So dont expect auto pot prices to drop if anything they will go up since there is more demand for them.
In old db hk/tw here was no free auto pots and for open chest you had to buy keys from cash shop no one cried about it because you had no voice here, and look everyone had money to buy autopot, omg how!? now you can get free auto pot for activity points but is still bad for some ppl, some ppl want everything for free, i expect some knowledge from moderators on this forum.
