I don't think this is just an issue with EV/KP. Rav/ToS are significantly harder than other veteran operations. Most will avoid them when gearing up in favour of the easier ops. Then when they progress through them there will be no reward. With galactic command Bioware have been encouraging players to do all content by giving reward roughly equal reward for the time spent and the difficulty. I think that is a good thing and should continue. With the current distribution that would not be the case. Discourage players from farming EV/KP, will only move them to farm TfB, etc. It would be better to encourage them to play all operations.
