Yh, I am now considering joining a pool for for the general sale of the expansion, although I don't know if I can with just buying ~10–20 CL packs. Maybe some of my thinking is due to FOMO, but I don't think that pooling charges more so I don't see any harm done—just added effort from myself.
I do understand the decision from a business perspective, BUT I also personally believe that the community itself, even without the participation of these large guilds, can fully sell out the general sale in a matter of days.
