Keep DEC or buy Dice packs?

I'm currently staking some SPS and i went yolo and bought 3 packs of Dice, i usually do that.. yolo.. which is pwetty dumb.

How are you guys doing it now? Are u keeping your DEC for the Airdrop points or are you buying packs?
Of what i've learned from this misstake is that it seems a bit stupid buying Dice because of the chance of getting good cards doesnt add up to the rewards of the staking SPS.

I haven't been getting good cards lately, i got 1 epic in three dailys , and i guess it's a good to waste the enemys first attacks while you get ranged attacks out.
