Nah, if it was the last option sure, but if they are going to put shards somewhere else than RF to begin with do it in real dungeons/raids.
It has been mentioned by several different people, myself included: Just put a weekly quest rotating five random dungeons (khitai, unchained, dragon’s spine) where you need to complete let’s say three of the five and you’ll get a couple of shards, or if you complete minimum three you get some shards, and then the more you complete out of the five the more you get. And this quest can be repeated on alts too, and the reward could be like 30 shards or something, it doesn’t even need to be very high.
But then again, I am pretty sure you’re aware of that suggestion already
About PvP tokens to shards I am not on board with that. I’d like to see them put -1000 PvP hit rating on the rings instead to be honest. If that would never happen yeah sure let the PvPers have a way to get PvE rings too
