there is a specificity to the lower tier that starts in DII... i saw it before hands in Asutria DII via the forum, and last season when i was promoted made the mistake to not use that knowledge. Lost a lot of money compare to others.
You can compare your prices with mine knowing that i would have liked and probably would have sold my lower tier at $24 with the champion boost for the fist part of the season. Maybe more, but then i could not be sure.
