Neverwinter is under going massive changes with MOD 16. The case can be made that change was imperative. Too much was out of balance. Most reasonable players would IMO agree with this characterization. Rather than point to specific changes that are debatable I want to focus on the root cause rather than multiple symptoms and provide a singular example.
Before a single line of code is written a philosophy of parameters is formulated. These act as the design template for everything. Rather than create a diverse set of parameters that would yield a rich set of choices for the players one of commonality was put forth.
The Paladin which was arguably the most flexible of classes has for all intents and purposes been removed from the game. It now shares a block mechanic and a divinity mechanic with other classes. The result is the most flexible class has been narrowed to have few choices. Use divinity and block to regain divinity.
I find this highly objectionable. Introducing a simplistic and highly limiting scheme for the Paladin is a class killer for me. I often see people refer to "cookie cutter" builds, this is now a cookie cutter class. One size fits all. Choice has been removed. While I am sure some segment of the player base celebrates the death of the over powered Paladin I lament the elimination of choice and creativity. Change should enhance the gaming experience not lobotomize it.
In conclusion, decisions were made up front that have resulted in what I consider to be uncompelling results. It will very interesting to see what the state of the game will be 2 months out from live. I might be way off base but I expect that there will be a dramatic fall off in what classes get played and by extension overall population.
