The campaign system in Neverwinter is actually pretty interesting. As I level my Hunter Ranger from 60 to 70 I’m mixing it up slightly by doing Tyranny of Dragons content (which scales for a wide range of levels), and the higher level Maze Engine campaign (level 60+).
The campaigns past the original leveling zones are a mix story quests and instances, and daily quests. Since progress on a given campaign is limited by currencies earned from the repeatable dailies, it’s not possible to rush all the way through a given campaign in too quick a timeframe. It’s good then to have options of other content to play in longer sessions.
I have had issues with power-scaling, the Tyranny of Dragons content is mostly easy to solo (Ghost Stories and other lairs being an exception to this), but the Maze Engine content has been pretty rough to play as a returning player. Monsters have lots of ‘crowd control’ type abilities, such as stuns or knockdowns and their damage output is pretty high too.
I’m working on improving my build as level and gear up, but for the most part I focus on the easier and more relaxing Tyranny of Dragons campaign. I certainly want to see the Maze Engine storyline, but some of the fights have been really tough. I even resorted to using scrolls of life in the most recent lair run: the Depths of Madness. The groups of demons in that place were vicious to say the least. It was good practice actually at kiting and using mobility to avoid as much damage as possible, but with the added restriction of staying close to the cleric NPC I was escorting it was touch and go.
The bonus XP over the weekend helped me to ding three levels up to 66 in a relatively short time, so well over half way to the goal of level 70. Having two different campaigns to work on with different difficulty levels, as the mood strikes me, is a good motivator: onwards to the cap!
