I am supporting this as it's exactly like Exo wrote: It feels like a punishment to get new dlc when this means to lose levels on my char. I own Genesis but I don't play it actually as there are no transfers (yet). Using Mindwipe i was loosing levels I had before. So I am now lvl 200 coming from 220. Reverse progress
Looking forward to an official answer as I don't see any impact on crafting bonuses as they are capped anyway afaik.
Edit: just saw Gunnsens reply. Doesn't change my opinion but taking note of it.
