Paragon Rankup Milestones in Platinum Track

Ashacekar

I see that Day 1 and Day 27 (last) milestone seems apt for Paragon which is 50% T5 CC, T6 Basic, and T3 Alpha.

But Day 7, 14 and 21 has T4 CC, T4 Basic and T2 Alpha. And that is same for TB and Cavs as well. I wonder if that's intended. For paragons, if not T5 CC (Weekly 50% would have been fine though), T5 Basics would have been good. I have lots of T4 basic in stash. For paragons, it is very easy to buy T4, T4 CC and T2 Alpha from Glory Store.

Just wanted to confirm the validity of rewards hence.
