A: We will not be converting glory boosters because we announced that we would be phasing out glory in John’s blog post and it wouldn’t be fair to the players that used up all of their boosters since then in preparation for it.
What this distills into is “we will not convert unused boosters because we indicated that there would be no conversion of unused boosters.” This is a dodge, not an explanation.
The players who used the boosters presumably already got a reasonable reward from it, which was the glory boost, and they’re still free to spend that glory. And as much as it might be somewhat unfair if they didn’t really want those glory rewards, it’s infinitely more unfair to give people absolutely nothing when they did not have the time to use their boosters. At the very least, you can convert unused boosters to some nominal amount of glory or other reward, such as dungeon tokens, or badges of honor, according to the player’s preference. There’s no excuse to take away leftover glory boosters and give back nothing in return.
Simply taking away a reward that players have earned is not only bad form, but this whole process of completely replacing a reward system seems to suggest that this game launched with an alpha version of PvP – which does explain its many shortcomings but is still no excuse to take away what players have earned. And that’s not limited to glory boosters, but also to the impending possibility of losing earned equipment and materials down the line. A proper phase-out should include ways to convert all existing rewards to something usable in the post-update environment.
