It's still an insane value. If you have all of these characters at G9, you're getting 5 characters brought to R5 which translates into:
- 800 Carbonite Circuit Boards
- 800 Bronze Wire
- 450 Chromium Transistors
- 100 Aurodium Heatsinks
- 375 White Signal Data
- 325 Green Signal Data
- 75 Blue Signal Data
- 500 Kyro (not including kyro between G9 and G12 - which more than doubles this number)
All that for $20 - which is roughly equal to 2800 crystals.
100 kyros would normally cost 2800 crystals. So JUST looking at the kyro you save on G13 finishers, that's worth 14,000 crystals - nearly a vault ($100).
Add in the signal data and the relic materials and this is just a stupidly good deal, relative to typical prices.
Cara is good in several teams, not the least of which is MM. Mando and Greef are clutch for the LV counter most noteably but LOTS of other counters as well. IG11 and Kuill will both be luxury relics for me - I've always wanted them at relic but could never justify prioritizing them - they'll go great on a dash team or droid team.
You'll get use out of all these characters with or without zetas. Zetas should not be the deciding factor here. It's a lot quicker to put a zeta on someone than it is to gear 5 characters from G9 to R5. Zeta later - jump on the deal if you have the money and inclination.
