###Notes

- According to [this answer][4], values do not increase if you already have all of the items in that category, which should mean that these will remain accurate throughout.
- The values in the table are _estimates_ and are not actual values. These values are used to predict what is likely better, but without the actual values, this is the best that can be done.
- Ultra-rare items are set to 0 for Veteran Packs based on [the answer provided by rare candy here][5].
- Formula used to calculate values is `Cost / Total Percentage` which gives the estimated cost per item level for each pack.

##Buying with Credits

For obtaining uncommon items or better, buy a Veteran Pack. With my estimates, Premium Veteran packs offer little to no value in terms of uncommon, but some value in terms of rare items. Spectre packs have a much lower value in terms of uncommon items (based on my estimates) but have a significantly higher value for rare items.

##Buying with (MS/Bioware) Points

Again, given my estimates a Veteran Pack and a Premium Veteran Pack offer little to no difference in terms of value. Also, as above, rare value is significantly higher in Spectre packs, but Uncommon value is also significantly lower.

##Summary

Buy Veteran packs to obtain Uncommon items, and Spectre packs to obtain rares and ultra-rares.
