How to get R4 materials?

I am a T.B and have just completed act 7.1
Is Loyalty, B G and Glory stores my best options to get T6 basic and T3 alpha catalysts to get R4 that is required to become Paragon ?
So best to give more importance to B.G grind or try to progress as much as possible in story quest? Suggestions needed

That is a good point.
There actually was a slight increase in r4/r5 material but mostly for paragon players , especially the ones that have access to advanced Bg, Aw,Aq wars or offers.
Even with that resources stay unbalanced, it is almost easier grinding t6cc rather than t6bc if you compare the quantity needed.

Monthly EQ rewards , Aq rewards , glory shop and why not , even summoner sigil really scream on an update in that direction for all players to balance the game .
If T.B, and new paragon players don’t have a chance to get at pace at least with R4 (now that R5 and 7* R2 are starting to be common in top accounts ) they’re gonna get bored soon …
