I really haven't run into any CC problem moments. I ran up against CC problem moments a lot more in D:OS with puddles and lightning than I have in this game. I feel that the tools in the current game make CC management really easy.
One of my guys in a lightning puddle? Frost armor and boom, effective character again. My tank takes too much CC? Give him all the mage armor. Problem solved.
In the first game, with random CC. I had little to no control. Now I have all the control and that is a huge improvement. I don't understand (and haven't seen any arguments except 'it happened to me') that support the idea that D:OS's random CC system gives the player more control than the current system.
However, I can support adaptations to CC in the form of more interesting conditions that may limit player concerns.
As to the other main ideas in this thread. I really do feel like proper play is the biggest and simplest solution and the early and original post were very childish. It has since become a bit more mature (while simultaneously more aggressive by some posters)
Solutions which make sense:
1. Pick the difficulty you want to experience. Exploration mode is exactly what the OP wants, and if he encounters the same problems in that mode than maybe we have another discussion. Since he never said what difficulty he picked I am confident to say he picked classic. Because of 'alpha' they haven't been explained during the choice and but are pretty straightforward (for those who had the same options in D:OS). I have often chosen lower difficulty in games that I have just started or purchased to experience the story.
2. More effort could be made with tool-tips/tutorials. However, the 'pre game' which Devs have already stated will appear before the island to help players understand the mechanics, isn't in yet. So this should help encourage players to control party members individually or in smaller groups while maneuvering in dangerous places. In addition, some words (I feel like there are enough already, but we still have this thread so..) on the importance of height and terrain would help to make people think 'hey, maybe I shouldn't walk through this narrow ravine with convenient ambush locations on all sides but look, stairs I can climb off to the side!" (this is the case with the current problem ambush)
3. After the above, people still complaining really have no excuse.
For my part, I appreciate how rough some of the fights can get, and don't mind an occasional reload. On that note, is there any places currently where you can buy resurrect scrolls?
