I agree, this sounds like an awful idea.
Maxing a title with 6, 10, or 12 tiers or a title that requires 1100 platinum to max or a title that takes 100 hours of playing to finish gets everyone 1/20th the way to favor for a whole
hour? That seems really ridiculous that such a colossal amount of grind is necessary for 1/20th of a reward which only lasts for an hour when the other 19/20ths happen.
Now, I also was thinking that they surely must have had statistics for how often a title is achieved when they made this decision, but I have a hard time believing that
maxing any of those titles occurs often enough to a decent amount of time where there is access to FoW/UW for everyone. If they said achieving a tier, i.e. Charmed qualifies as opposed to only Blessed by Fate qualifying for an drop in the FoW/UW access pot, I would totally believe that achieving a tier happens often enough to be fair and provide sufficient access. However, by only having
max titles contribute towards granting access for everyone, the system is impractical because it 1) does not give credit for people who already maxed a title before this change and 2) given the amount of time to max an average title, it seems unlikely that favor will be able to be granted for reasonable amounts of time and 3) unless they keep adding new titles periodically until the end of time, eventually everyone will have all their titles maxed and favor will be impossible to obtain.
I cringe to think of someone's name being broadcased in every spam hub and FoW/UW entrance. It probably sounded like a nice idea, give someone a pat on the back in front of everyone! But it's not a very good idea after all, because it's more spam in spammy places, and because it will probably generate more "Thanks for title spamming my city, loser" PMs to players when they get an achievement than anything else that would be appreciated by players.
I appreciate ANet trying to make a change that people have wanted pretty much since the game was released, but it seems that they will really have to change the mechanics of favor in a few ways in order to not make people even more upset than they were when PvP achievements determined favor. Either that or they need to reallllllly increase drop rates on FoW/UW scrolls
