T6b and t3a disparity
With the introduction of valiant daily crystals the balance of t6b and t3a can quickly become uneven. It appears that spending them you still need equal amounts everywhere and up until this point, with exception of banquet last year and I would assume this year, acquisition has almost been even with a few exceptions that are minimal.
I explored necropolis and became valiant in the first week of release and since then from daily valiant crystals I have obtained 3 full t3 alpha more than t6 basic. You can overtime balance it out (theoretically) from using glory, bg tokens, and loyalty. However that would force you to spend currency on items you may not want to spend them on, or allow you to buy half of what you would like to. If you wanted to max t6b and t3a from the bg store each week, you would never make progress so you could only buy the resouce you were short on. Yes naturally you would also expect to balance it out from daily valiant crystals alone, however we won't be opening nearly enough to even approach an average pull distribution.
I suggest a simple solution that is already available for lower catalyst in the black iso store. When it is updated for valiant players, hopefully soon, a 1 to 1 trade would be a great pro player move.
