The CP power creep is out of control. ZOS has recognized this by beginning to eliminate CP from Battlegrounds and various Cyrodiil Campaigns. It's time to remove the egregiously OP power creep by making the CP system a series of constellations of quality-of-life passive abilities. Scale the number of Champion Points down from 3600 to 360. Remove the cap. Every 10 points added to a Constellation unlocks only a passive--no more attribute increase or skill increase.
Keep passives like Windrunning and Master Gatherer and add more similarly designed quality-of-life passives. Remove damage passives like Exploiter.
Voila. Game balance becomes 100% easier from that point on. ZOS doesn't need to worry about the next CP cap increase and how it will affect future and current content. Classes can be balanced within each class' internal mechanics.

Sias - Sorcerer / Prefect
Short answer is DKs likely won't be seeing a ton of changes before we go live; this class is still quite powerful (as it should be being a tank), even after some of the adjustments we've made to other classes and abilities.
DK IS NOT JUST A TANK CLASS. #PLAYTHEWAYYOUWANT
