I played during iCBT2, but didn’t get far enough to experience the importance of dungeon runs xp-wise. So I don’t really have an opinion on the matter.
My main concern isn’t only the reduced number but also the 3 extra with token, it doesn’t seems fair (3 free and 2 extra with token would have been a bit more fair in my eyes). I do think that buffing field EXP is required as well, but again, not enough experience to be sure.
Edit (cause your edit): IMO, you should have extra with token, IMC need incentive and value for the tokens. But having more extra than normal doesn’t make sense, yep. As @daimian_nightwing suggested, 4 runs with 1 extra seems the most reasonnable.
I really like that ! I play MMOs to meet people and play with them, having to use cross-server matchmaking (without the option to queue with friends) to be “optimal” is a real let done for me.
