Based on opinions I've seen here and elsewhere, I think there's probably more like 900 sides...
that's the big issue... trying to box off people.
We see it all the time with every issue... if I for instance say that I want a more advanced and more thorough ground floor rewrite, I get told my opinion of a class doesn't matter since "I am not the customer base" but if I say I like a change (unifying subclasses, the rogue overall, the ardling) I get told it doesn't matter "I will but it any way"
The truth is much murkier... my group is very uncertain... we had (as a much larger group) mostly moved on from D&D3.5 by the end, and halfish of us came back for 4e... most of the ones that left for pathfinder came back for 5e, and that pushed a bunch (but not all) of us to update... now 5e is grating on us all in different ways, but we don't want to split 4e/pf again... so we are not sure what D&D will be. However as we have looked at the playtest somethings we liked some things we hated... very little we loved.
This is the first time I have heard about a D&D upgrade I wasn't excited about it... instead I am afraid of it mostly. I was a driving force to updatge 2e to 3e and 3e to 3.5 and to come back for 4e and to get the gang back togather with 5e... now 1d&D I can't be cheerleader for, and my group doesn't have one yet.
