The FoS criteria is a little inconsistent since the 3 drake OS mount was never a FoS like the equivalent mounts from Yogg and LK.
I guess if you want to show you got your mount when it was hard you can link your heroic Rag or DW ach and tell people thats when you got it.
I don't care about others seeing my mounts as long as I like them. I'd like opening my FoS tab, seeing the achievement for the Armored Razzashi Raptor and think "Aaah, yes, that took a lot of time to get!", and be proud of it once more. *Single tear drops while gazing the horizon*
The reason why so many drop mounts don't give a fos is a mix of laziness of blizzard's part(they do not care for mount collectors at all and when they do they give reskins for achievements) and then just the pointlessness of it. Why should every drop mount have a fos tied to it? It loses all meaning of a fos when you can get 30+ fos just because you got lucky. The mounts themselves are enough of a reward, they do not need a fos tied to each and every one of them when people do not care about a meaningless achievement you can link when all people want to see is the mounts.
Of course they added FoS for completing a raid on normal during the tier which is basically just to say "Hey I was in a guild and we raided." Something that could also be done by looking at the time stamp of a normal achievement.
And now blizzard even adds a shitload of feats of strenght for people that kill a boss on NORMAL before the next patch comes ? PVE PLZ ...
So yes i would like to get an special feat of strenght for my 4/4 zull gurub mount collection. Whilst i only got credited for 2 outa for due to blizzard laziness.
