The individuals dissapeared from the store like one year ago, if my memory serves me well.
I find myself in a similar situation, but I only lack Marcus Furious (except for this year new minis, that is). Funny enough, I bought Infelix in the order I was going to buy Marcus, but he was out of stock. Then, they both were removed in favor of the starters.
I get the bussiness reasons behind this decision, but It's taking a lot of thinking from me to buy two minis I already own (and have one painted, even), to get just one.
On the other side, I applaud their decision to make the new helleniki starter with new minis, instead of the ones already existing. I bought all of them at the same time except for the mount, just in case they ended in a starter and I missed someone else
