But i can still run the old LFR where the charms are used. I can get a key (only one this week from a rare mob) and run the scenario that will allow for me to collect more Elder Charms, but is easier to do with one or two charms on hand to buy extra bonus potions that make life easier.
The point is that just because the new content is out doesn't mean the old content is now completely outdated. For many it is still viable gear. The complete removal of the quest was a bit of a bad choice. Keeping it in and scaling it down (get less from a turn in, takes less lesser charms) would have been a better choice. They then could have phased it out at a later patch day after people have had a chance to get into trove (i.e. this next tuesday or the next small patch day).
