Day 65. Level 50. All Impoppable maps beat. No TCW

I am on day 65 with no way to effectively earn epic orbs and still have not seen the TCW. For the last 10 days I've been logging on solely to check the shop and see if I got lucky. Now I'm left with the question, what's the point?

I rerolled through most of my epic orbs looking for the elusive TCW. I passed over multiple Googoomamameters among other core items. Even by passing things up, I managed to easily dominate the final levels through gear I picked on rerolls.

After beating all the impoppable levels, what's the point of trying for TCW? Epic orbs become extremely difficult to save for. Quests give trash rewards and so do beacon levels. Why should I continue to play?

Add more content please. This is the best tower defense game ever and I hate having to log in daily to check if I got lucky in the shop.
