With the destiny changes, some things have become less available for people to get due to the lack of twists of fate and trees oftentimes not having the necessary enhancements. For example, to be able to get cocoon and near as much reflexes as I used to get for my evasion build, I have to be in primal avatar, draconic incarnation, and shadowdancer, but that takes away by divine energy resistance, 25 PRR (of less than 200), 15 MRR (of less than 80), around 1/3 my HP, will saves by 12 against meaningful spells to avoid, among more just to do, when due to physical limitations I can't use the epic strikes and other temporary buff added in the new system.
For the recommendation, I would like to propose adding in cocoon as a tier 1 destiny feat, and saves by a decent amount (like +5 or +6 that stack with other sources, just as epic feats and destiny enhancements have been doing) as epic feats. This way, people can use those abilities that have become regularly needed for content and be in destiny trees that are actually important for their builds.
