What the heck is the deal with those? They're BOP, they're an outfit style (meaning way moar pages than a normal motif, 1 per weight etc), they drop only from the BGs reward coffers that you can only get once per day (per toon, but still) - and, in addition to that, it's not once per day after reset but once per 20/24 hours so gods forbid you can't game at your usual time one day - you're gonna miss out on that coffer then. For me they only ever seem to drop like every 5th or even 10th coffer (I didn't even realize Horned Dragon was actually a thing til like a month of daily BGs on 2 toons). So...if I counted right, there's (7 armor pieces in 3 weights + 10 weapon styles) 31 style pages, so 62 for 2 styles...with droprate like that it'd literally take years to get all of them with no way to speed it up other than making 18 PvP toons for daily BGs.
Did I miss something there? Why on Tamriel would you do that?! It's not like they're even best motif in game or anything, they're simply a very slight reskin of Fang Lair/Scalecaller Peak motifs which you can farm just fine with no cooldown or need for alts. Why would you gate something like that behind such crazy timesinks?
All I want is Fanged Worm chest - in either weight, really, although heavy kinda seems the coolest - because I love the looks but the original Fang Lair version looks too bulky with those books at the hips, Fanged Worm looks much better with the alchemy things. But dat grind...that's just silly.
