Can we get more Bonus XP Tiers?

There are 17 days left in Season 1 and I thought there was more than 740k XP, so I had traded all my collectibles in for Season 1 Tokens- hoping to get 5 of them to upgrade Demko from 84 to 85.

Last night I hit 740k, got 2 collectibles (2/5) of the way to the next token. As I already have 4 tokens, I thought getting 2 more levels would be doable before Season 1 ends.

Then my disappointment hit when I saw that I was at the end. I'm now stuck with 4 XP tokens, because I can't go back and turn them back into 20 collectibles and I cant use them to upgrade Demko further than 84.

I'm sure that I'm one of the last players to reach the end of the path. But with two weeks left, and no XP to earn. What incentive is there to play? I was really hoping to continue to grind for collectibles and the 3 x 78+ packs.

Please could you add at least 5 more bonus tiers? I think the players would appreciate it.

If not, can we have another way to get XP Collectibles? I only need 3 to finish Demko.
