These are my opinions on the update and my experience playing mod 15.
First off the instructions for the new crafting system is not good and does a horrible job explaining all the ins and outs of the new system. Secondly, there are some bugs that result in not being able to move forward with the professions is quite frankly annoying and should have been resolved prior to even launching this on console. Third, the system is wonky and not much better than the older system. A crafting system in a game should not take hours to actually figure out and it should be fairly straight forward. My experience with the new the crafting system is horrible and IMO just as bad as the prior system. You should seriously look at other games crafting system and take a page from their book on crafting.
Class Updates - OMG you seriously made CW way to powerful. DO DC are also in that category (especially if a player is properly built). There was no balancing done here and things are just as bad as they were with prior mods. I mean honestly how can you say you fix something but allow a class to hit a sparring target by over 10M without any buffers around them when previously that same class hit for under 3M. That is just bad coding or class mechanic design.
The campaign for mod 15 is clearly for lower level characters and that is fine, but the story for the campaign is just plain old stupid and silly. I honestly don't even know why this was created. With all of the various content available within the Forgotten Realms and in other D&D campaigns you deliver this content. The worst part is the reuse of maps and than adding the annoying voice over to the map we already played a few thousand times is just well quite frankly more annoying than dealing with the bugs from the crafting system.
I'm going to continue playing and seeing if this gets any better but while I was playing around with mod 15 updates for NWO yesterday I was watching ESO 2019 planned releases and that looked more like how a developer should handled content release. In fact, it got me to pre-order the new chapter coming in June and I'm just starting out in ESO compared to NWO where I'm an end game player with 3 characters all over 17K. Since mod 15 doesn't seem to offer much for a player like myself and after completing the campaign I really don't have much to run I guess I will have to sit pretty until mod 16 comes out.
