You are either griping about 1 of 3 things.
1. They said everything must be portable. THIS MEANS ALL MY PCS. Not one pc can be hurted by any season flair. My PC can not be hurted at all.
2. You are griping just to gripe the portability issue...
3. My PC is wanting to farm items from select modules.
unless my maths is wrong. You be in Tier 3 before you get to 150 days. Unless you getting min xp.
Assuming, of course, you can find an AL DM to run more CoS adventures after you accepted going on the first one. Cos award kept me out of AL for that season because my public table time is inconsistent and I didn't expect I would get in enough adventures to manage to leave the demiplane. I could bother to develop a larger stable of characters but my table time is limited and inconsistent. If I'm not advancing the PC I want to or have another overriding reason to play (like a friend wants to ) then I'll find something else to do. I'm not going to start a CoS game if I think my PC will end up abandoned because I miss the next 3 adventures and I am unsure if I will find someone to run them when I can make it. Similarly, I'm not going to run a ToH game with a character who's died because I don't know when or if I'll ever be in a position to relieve the death curse.
