Previously I have not been interested in the ultimate pass, I always earned enough levels to get what I want from the pass without needing skips so they hold little value for me and I’ve been content to get the seasonal starter pack to get coins for the BP and to get a new skin each time.
With that mindset when I logged on this season I had “new” flags on the battle pass and shop. I went to the Battle Pass first and received my banked tiers and then so I didn’t forget and miss out on the 20% XP I upgraded to the premium pass.
I then went to the shop to check the prices of the Lilith and Inareus skins. Then I discovered they are only in the ultimate pass. The ultimate pass includes the premium battle pass too but I’ve just spent 1,000 coins on that so it is marked as owned. I click on the purchase and the price doesn’t change unlike bundles for coins when you already own some of it.
I think that there are 2 potential solutions to this. An upgrade bundle where later in the season you can get the ultimate edition and if you already own the premium battle oss it is slightly cheaper (there is precedent for this with ultimate and invasion last season, the ultimate upgrade was offered for the price less the invasion bundle cost if you already had bought invasion). Or the potentially simpler solution, if you already have the premium BP you pay the full price for the bundle but get an extra 1,000 coins to refund the duplicate premium BP.
I haven’t bought the ultimate bundle and now I don’t intend too without a change (also not purchasing the starter pack).
TL;DR - if you already own the premium battle pass you should get 1,000 coins instead of it from the ultimate bundle should you decide to upgrade later in the season.
