Torrential Fragment drop rate is insultingly low

I’ve seen a few forum posts about this topic but I also wanted to throw in my experience on this. My main issue with this item is that not only does it have a ridiculously low drop rate but it, and all the other runekeys are SOULBOUND rather than WARBOUND which makes no sense for a zone that’s almost entirely designed for gear and alt catch-ups. Blizzard I’ve been at this farm for the last 5 hours and I’ve only gotten 1 fragment so far using the northern area of the Siren Isle with the Vrykul enemies and the rare Squid boss that spawns southwest, either you increase the drop rate across the board or you reduce the number of fragments needed from 7 to like 3 or 4 because this is just getting very absurd and just extremely demoralizing to farm for. My biggest fear is that I’ll be doing my dailies on my alts and then actually get one of these fragments randomly and not be able to send it to my main. I don’t know I just think the way you guys originally thought of how you’d want us to obtain this mount contradicts the whole design philosophy of the zone itself by making it as least alt-friendly as possible for no reason at all.
