Fun is relative term. People are here for the DnD 5e rules not some bastardisation of it.
And if this is done for testing then its not a waste of time or resources but valuable information gathering.
Hi, I'm not here because it's 5e. The name has more to do with why I'm here than being D&D or what edition of D&D.
Hi I am here for DnD and 5e.
Excellent, I won't try to force what I want to play on you, and you can do the kindness of not doing the same to me, deal?
