Just to clarify my point, when XP or packs are awarded, remember you have to go in and click claim for them to actually be credited to you. All I’m saying is it could be fine for you to log in, let them come through and leave them unclaimed. (I have a bunch of unlimited time ones sitting waiting to claim when the new season starts)
You can even leave card packs unopened in the store as well if you wish.
You also may have some rewards that come through that have a time element to them, ie they might be about to expire. Therefore once the new season starts they won’t come through anyway as they are expired. If any of these are card packs then you potentially lose these.
Hopefully that’s a bit clearer
