@XHelperZ there were only packs up to level cap of 500 in the old system. I was above level 1,500 too.
As best as I understand it for now:
I think the old level 500 gave around 199 packs.
You would add bonus packs, BP packs and bought packs to that.
The new level cap will now be 2,000.
The new system rotates through 500 levels four times.
The level icon also looks different each time, indicating which of the 3 new levels you are on. Green for me at the moment
I need to find out more about the icons.
Players that had the old 500 levels done already, will have an extra 1,500 levels to unlock.
There are 345 extra Apex Packs now available to us.
I have yet to see at what levels the new system delivers packs, in its entirety.
199 plus 345 = heirloom 😃 (or earlier)
