Without including the 50 from login, from what I gathered so far I can get between 1-3 cake slices drop every 3 min and a buff every 5 min, which leads to 7 cake slices when I get the lootsplosion on the 5th buff.
Can SIF speeds things up ? Do we know what is part of 3rd year cake ?
I will go for the cap team up and the stash, but I don't think I am gonna go crazy farming for cakes honestly. It's just too slow and demotivates completely.
Seal speed with 2 per boss, and the missions for 15 had a much better pace and were more fun to farm.
