Infinity Dust Shopping

So I have 3M Infinity Dust. What's the best bang for your buck?
-3500 5-star shards and a 4 star Awakening gem?
-5000 5-star shards?
-3 t4c crystals and a 4 star Awakening gem (or 1 t4b)?
-5 t4b's?

I'm at 260k rating, all my top champs are 4 stars 5/5. Not one rank 3 5-star hero yet
Ya T4CC is what I'm leaning towards, hardest thing to obtain in the game for me (other than T2A catalysts)

Go for max t4cc possible, left over use in 4 star awakening gem, t1a and 5 star shards. Stop ranking 4 stars unless God tier with possible great synergies. Time to rank up 5 stars wisely.

A little confusing (the answer is probably somewhere but I can't find it)

The store says 5 days left to spend the dust..
But the in game message says to spend it before the 6th of June (in 3 days)
Which is right?

spend before the time in the store goes away... regardless of any message you receive.
