@Dirtbag_Leader the IAE CCU Warbond Polaris from Hull-E is not a 25$ CCU worth 100$. It is a CCU just worth 25$, its melt price. The Hull-E from upgrade matrix is at 650$. The Warbond Polaris allow to get a Polaris at 675$. So the warbond CCU Hull-E to Polaris is worth 25$. That is all :) But i understand you meant 'worth' by the bargain it gives compared to a full priced credit Polaris.
@Sirus7264 If he melt it, he will have to pay 25$ to get it back. He was just mentionning the 100$ as the potiential economy compared to a credit Polaris @750$ (vs 650 Hull-E).
edit : the funny thing is that the Warbond Standalone Polaris from IAE is at 675$, when the Warbond CCU to Polaris is calculated for a Polaris at 700$. So actually this means that Dirtbag_Leader might have used a coupon, because the IAE Warbond CCU Hull-E to Polaris should be at 50$ (i bought my IAE CCU Warbond Carrack to Polaris for 100$ melt value). In that case, Sirus is right, you will have to pay 50$ if you melt it and want to get it back.
