OW1 transfer to OW2

I didn’t knew that OW1 is going to transfer to OW2 .
I had 375 legacy credits and I wanted to play and get 1000 LC to buy karasu-tengu,
and I tought that I have all the time to get those LC but when OW2 came out all the skins prices go up and I didn’t have a chance to buy this skin.
