Rep and reknown feel so simmilar in function that I feel combining them and continue to update and think about this system doesn't sound to bad. Rep could still work in a sense it's bound to major story elements. Not tied to weekly resets just your own time. obviously the grinded feel on it should need a nother look for it to feel fun and not I have to do 80000 dailies so I get exalted for best rewards.
Covenants were not a bad idea, the thing that sucks with covenants is that it's not cosmetic, simple. We should have just gotten a new abillity per spec or what ever and keep it instead of these borrowed abillities that are tied to that covenant.They could have gone a differnt route and allow us to alter excisting abillities BECAUSE we are now allied with these mysterious shadowlands races. Greenshadowy Mind flay instead of blue one, or Venthyr looking fireball (could even alter name) The all around abillities such as venthyr teleport and kyrian healing pot would have been enough alone. More like flavor.
The key thing for future covenant type of content is that we need more frequent updtes and extra things to do, with cool rewards. Sl tried to do that, but it all felt very sparse and unexciting. Sl failed at giving us cool things to do in this DEATH themed expansion. It lacked on all fronts. You know..at some point you were just done with them.. storywise, but also the intrest was gone.
