I bought the $100 1+50% crystal pack and got 17 uni's and 4 packs of the CCF limited sale. I personally believe this is the best bang for your buck and the opportunity comes once every 365 days. The deluxe packs will always be there long after this week is done so i will get the psylocke pack later when i get enough crystals again (im saving 3k in case the CCF package comes by again before the end of the week)
I basically did this - I bought Mag pack over the summer and used up $50, then like 1 week later DP epic quest was announced and then I bought that. The additional 'content' and the first time rewards are really really nice. Overall, it seems daunting but IMO it was worth it (really wish they had a crystal sale when i did it and i bought them both together tho).
