My best guess at upcoming classes

Based on this and on what was originally released in KR and what would be up next on the list my guess is Summoner and Arcana would be next, but I highly doubt we get 2 mage classes next back to back.

right after this would be Reaper and Scouter that were both dropped in KR at the same time. (If i am remembering correctly)

So if I had to guess we will get a combination of either

Summoner and Reaper (the classes both shown in the official PVP video)
Arcana and Scouter

Obviously, I do not mean in the same month but rather the next ones to be announced if we get another 2 month’s roadmap.
