LET PEOPLE CHANGE CLASS AT THE START OF DELUBRUM

[Alleo]

It does require at least rank 10 and a run of castrum to unlock, and I don't think someone will have made it to rank 10 and through castrum with 0 fragments. The quests themselves award a few, as I recall. Granted they may have fragments that aren't exactly optimal for any particular kind of loadout but if these are players who don't really care about bozja or castrum we're talking about here, they can just use anything at all and it'll help. There isn't a particular need for them to be concerned with running out or using their good stuff before they need it because they're never going to need it later.

Fragments that some might have already used on their way to unlock castrum. And it also still depends on RNG. Also what if they do use the good stuff in DR and its a failure run? Suddenly no actions for the next try.

And all of this ignores the good argument someone else already posted: If you queue as a DD you might simply not want to tank or heal. What if everyone is like that? Who will do it then?

Iscah also had a nice idea with giving certain builds that will already have these skills.
