DDO is not 5th edition so theres no real reason to qoute it. 3rd edition mechanics and 5th edition mechanics are not really compatible. 3rd edition was much more about character customization and on a much higher power level on the whole.
and yes actually it does matter because wizards will pressure them to use raw as much as possible.
I forgot to mention barbarian using reckless attack to force advantage. with the added hp and rage to protect the rogue from dying.
We arent talking about what all kinds of DM's will do, we are talking about Larian and what they will do with a very weak RAW class. they are doing work on ranger and im excited to see it. im just hoping that how bad ranger is doesn't hide monks poor design as well.
Multiclassing in 5th edition is actually looking very crap to me. It was my favourite part of both NWN games and DDO.
