I tried the demo and really enjoyed it. I tried solo all classes, played coop with friends, we had a blast building up and fighting the boss. So I bought the game... and it's all gone (in the full game version). 6 hours of hard earned progression, upgrades, sweet loot - I have to repeat everything.
Worst decision (and a rare one compared to maaany other demos) the devs could have made. Why? Is the code / savegame data so different, technical limitations or do you just intended to wipe hours of playtime for someone willing to spend money on this game? I don't get it :(
