Are you talking a Level 1 Rank 4 to a Level 1 Rank 5?

There really isn't a master list but I believe 14,000ish A-Coins ($100) will go from Level 1 Rank 1 to Level 1 Rank 5 assuming you have the gold already and are only upgrading for missing cards and level ranks.

I think it will be difficult to find the exact information you want.

I'm talking about from lv 7 rank 4 to lv 1 rank 5 

Don't quote me but when I did mine I think it was around 1,200 A-Coins

To me it was worth it as getting energy capacity 12 allows that mech to shine with higher DPS weapons.  Shotguns are not bad either if you are stuck at Rank 4 as well.

Yea I use my shot guns on my kill shot.. beings that its a ability is close ranged, seems pretty effective at the moment my total power is just above  1600...

But im trying to get my shadow to rank 5 to fit both right lv 6's for a bit of range and like u said higher dps.

I run Missle-Rack 6 (x2) on him.  I find it to be pretty nasty assuming you can flank the enemy team and cause havoc in their backline.

Won't be much longer
