I know exactly where you're coming from and because I have all 3 different types of character I wanted to collect all specific strike armour and I did. The feeling is great my titan looks like a beast with the darkblade helm and the mau'aul gauntlets and I'm one of those people who got extremely lucky for both drops it took me about 50 strikes for the darkblade Helm and 50 strikes for the gauntlets. My warlock looks awesome with electricity flowing threw its face, again was lucky since I don't even like doing the SABER strike about 25 of them and I got it. Last but not least my Hunter, he looks amazing with the solar flayer mantle and because I'm a collector I wanted the other two the void and arc mantle. And let me tell you the grind was real I started to try and get void and let me tell you it took about 150 dust palace strikes, some of them heroic and this weeks nightfall (and nightfall does have increased chance for strikes specific loot) before the damn thing drop, the feeling was amazing and lucky enough I help my friend get the arc mantle and found an arc mantle in my post master. Soo i understand every bit of frustration you have. It feels like the thing you want most takes the longest. I got my taniks cloak at 75 strikes. Anyways all I have to say is keep at it don't stop you WILL get it eventually. And if you still don't get your gauntlets by the time the brother strikes becomes a nightfall then grind the nightfall it has in insane increased chance for specific strike loot to drop. Hope this helps Have a nice day : )
