So, I already made my piece known on Holy Burst, and we can see how exceedingly successful I was with that. Oh well, I run my Silver Flame Favor I suppose, and no one Premium manages to craft it without paying extra - the man wins.
But I'm moving on - let's talk about the Shards in the OP:
Greater Lawful Outsider Bane
Large Devil Scale
Greater Dragon Bane
Flawless Siberys Dragonshard
All other ingredients aside, let's talk about those.
Now, finding "Holy Burst Silver of GLOB" with any +Enhancement bonus out in the wild? You're more likely to pull a Litany. Pretty rare, I admit.
So, what choice do you have if you're not a Paladin w/Holy Sword? Well... you want to bust DR. And you want to do damage. MoPG is an option for Busting DR, but not really for doing damage. Your Flaming Burst of GLOB does good end numbers, and ensures a high to-hit, but ... doesn't break DR.
So your best choice? Craft a Min II. The Acid isn't *great* against Devils, but it busts DR, has a high base damage, has Holy, and no one will question you using it in Shroud/VoD/ToD. But ohdear... the cost. 5 Large Devil Scales, and an assortment of other larges? That's going to be expensive. Oh, I'll just run Shroud, and see how long that takes to get.
[Sidenote, since most forumites don't know: It took me 40+ Part 1-4 farming runs, and 16 completions, before my first toon saw his FIRST Large Devil Scale. Even back to back, that was 48 days. For one.]
Oh well heck. I can't pull any LDS... oh wait! Cannith Crafting, that's right! I've taken all my mats from running all these Shrouds, and all my other quests/raids/epics, and deconstructed them! I've also bought some from the AH, and maybe from time to time bought some from other players, or used an XP pot from the guild store. I've invested a decent chunk of time and plat on this, and prevented myself from earning plat by not selling high-value items to the vendors.
Yeah - that sounds good. I'll use Cannith Crafting, so I don't have to keep getting disappointed by Shroud's lack of.... Large Scales. [Insert your favorite four letter word here.] And now that I've used all my money/random loot on Cannith Crafting? Well, I don't actually have the funds to buy one from the AH. So, nuts to that.
Greater Dragon Bane. I'll keep this one short. No one in their right mind is going to trade a level 20 Feat Swap to **** a single dang shard. Especially when a Lit II outperforms +5 Icy Burst + Axiomatic Burst of Greater Dragon Bane vs. Epic Velah. (There was a thread on it, if you're that interested look it up)
TL;DR - If we invest the time to level to the appropriate Cannith Crafting level to make these high-level shards, don't punish us for having done so.
