For anyone asking regarding rest of the updates that we announced for 3.0.

Group Summon and 8 gates runes shop were both delayed and pushed back due to serious in-game problems.
New Group Summon will come later during 4.0 version. As for Shop Runes, at the moment there are no information I could share with you regarding this update. We will update you as soon as we will be able to.

Hope this clears the confusion, have a nice day everyone.
