I've been talking to a few people over the requirements for the achievements, and we've come to the consensus that most achievements are perfectly fine. But there are those select few which are so awfully time consuming that most, if not all, players won't even look twice at them. Which for achievements, isn't very good.
Let's walk through them.
Battle: Everything in this category seems perfectly obtainable , even fun to do.
Character: I'm sure every has some want to get all their jobs to 50, it is natural, at least to me, to want to shoot for these achievements. DOL and DOH will be the most time consuming, but it has a lot of rewards in the end
Currency: This is were it gets a bit, umm, ridiculous. Especially the two 100,000,000 gil achievements, Who Wants to Be a Gillionaire and Never Met a Corpse I Couldn't Rifle. I understand the devs want the players to do these, but even if leveling every job to 50 from levequest, this would never happen, not even mentioning no one wanting to do so. The second one is even worse, having to kill humanoid enemies to even get gil from drops is bad, but needing to get 100,000,000 gil? I understand why the devs chose to not make every mob drop money, so not everyone one was rich, but come on.
Items: Honestly not that bad, yes you have to do a lot of faction quests for the items, or a lot of money to buy them, or friends with the items already, but it is entirely possible. The faction levees take time, to get the points for, and to do, but it really isn't that bad.
Synthesis: Again, very time consuming, but possible. The golden tools may not be the most fantastic thing ever, but it isn't too hard to get. Especially since you 90% done just by getting to 50.
Gathering: Way worse than the above. It seems kind of ridiculous to require 4000 gatherings in each land in order to get the golden tools when compared to the requirements for the above, Synthesis, tools.
Materia: I'm not sure how I feel about having to affix 1,000 materia or break 1,000 spiritbound items into materia, but it seems feasible, or at the very least possible. Even having to affix five matiera to one piece of gear isn't that bad. You just need time and a little luck....and a lot of materia.
Quests: Getting the Chronicler's Crown seems fine enough, the real problem is is the requirement for 10,000 regional and local levequests. Many people use local levequests for leveling up their crafts and gathering classes, most people do not level their main classes with regional levequests. At both ends, needing to do 10,000 is kind of ridiculous, not the worst, but still not really worth it. Same with the Faction levequests, you'd need 50,000 points to do 500. Which requires really getting the past achievement of doing 10,000 levequests (actually around 9,000). Not even mentioning only being able to hold 99 levequests. Achievements should take time, not this time though.
Seasonal Events: I think people who missed out should be able to get them the next time around, but I don't see a problem with this one. It is very easy actually.
Dungeons: Naturally done. People may find it a bit difficult to do the 5 chest runs, but it is actually very feasible.
Exploration: Probably my favorite out of all of them. It is difficult, and require patience, but it can be done and is fun to do. I only feel bad that most of the world that is out there isn't used for more.
Grand Company: Probably the worst overall category. Needing 500,000 Seals, 500 company levequests, 5000 of each mission (supply is probably the most feasible) and 10,000 packs? Crazy and not really feasible at all.
The problem is, for most of the ridiculous achievements, all you get is achievements. There is nothing to make it worthwhile. And even if there were, requiring that much just puts people off, it doesn't make people want to do them like achievements should do.
I'm not asking to make everything easy like most people try to attack OPs with. I want achievements to be feasible. If they are to be time consuming, don't make it ridiculously so. If they are to reward me with something awesome, make it actually awesome. If it impossible or not worthwhile then there is no point in doing them, thus defeating their purpose.
Thanks.
