Ahhh... The monsters! That's the meat that's missing for me to say how I think 5e is going to turn out. Trying to analyze the game with only one side of the equation is really hard.Mike Mearls has said, repeatedly, monsters, magic items, and encounter building stuff will be added to 5B when the PH(B) launches.
Thaumaturge.
I talked to a couple of my players, and they aren't that fond of what they have seen of 5e yet. I can actually understand it. One of them really hated starting campaigns at level 1 pre 4e. I am pretty sure we are going to start at level 2+ most of the time.
Personally, I am a bit sceptic, because I am quite sure they will have bungled the math on when you look at PC vs Monster. It might be totally unimportant due to bounded accuary and easily fixed with an adjustment to xp budgets and challenge rating.
The reason I am sceptial is that they haven't done a test with a large number of players like they did with the mechanics. Looking at the Hobgoblin and it's CR/xp showed to me that they were quite off. Will have to actually play test it to be sure though.
