Once BF is done and dusted, I think I'll be relatively happy with my team, and moving forward, will probably just be looking at buying the occasional high level IF to improve it. With this in mind, I was thinking I could start saving my packs, or at least the 35k+ packs, earned from squad battles, SBCs, Weekend League etc, to have a huge amount waiting for the TOTY event in January.
Now I'm sure I won't be able to maintain the patience to actually do this, but if I could, is there a limit to the amount of packs you can have in your 'my packs' section of the store? I've seen a lot of Youtubers do videos on '100 gold upgrade packs', but they could just be stopping at 100 because it's a nice round (and big) number. Also, I heard the pre-order packs expire after a week if not opened. Are any other packs like this?
