This "small" event is like an Expansion to me, please make it longer and keep the classes.

Please do extend the duration, 1 month to test out all these characters? Not enough!

I really do think you should keep making and keeping these "new" classes around, because that`s what they are to me and this is what i get hyped about, not the endless grind at endgame.
No matter how good the endgame is, it will become stale after a couple of weeks but what will never become stale is making new characters.
Each new character comes with a new vigour and you just can`t wait to get to a point with each character to restart that vigor.
That is main draw for me in arpgs and i really, really hope that you keep making these "new" off classes and making them official even if in a side format.

You might not realise how big and exciting this is.

make them a private option, don't put them in the main game

they alreadyy said

it is likely to become a private league option in the future

and

they might extend the league if its popular enough
