I've expressed this via PM, but with the recent DM comments—thank you for contributing to the dialogue!—I feel it necessary to repeat it here:
Having the ability to submit DM-support requests is awesome...but not really awesome if your Guild has to wait 6 weeks for a tangible response.
THIS is the issue why players call out for Guild DMs, I imagine, because it does seem like the current DM Team would prefer to run their non-guild based Events for random groups over supporting Guilds attempt to RP with the available world (NPCs).
This stands outside of when Guilds ask for things that just are not gonna fly on this Server, half-baked ideas, or outright fantasies that have no place in this fantasy world!

All which should be easily and swiftly receiving a HELL NO response.
The response so far, to my privately sent statement repeated above, has been: overall, there are too many requests for the DM Team to answer, or to handle, or essentially to support. If you want to see the exact quote, I'll provide it. And, if this is
the real underlying problem why Guilds suffer the lack of DM attention, then...what are the possible solutions?
A Player and/or a Guild can get a massive amount of RP accomplished in 6 weeks time. But they cannot do that if there actions are bottle-necked by hanging on DM response—and I mean response, not a Yes or NO, but an actual response! Meaning as well that results come much later!—else the Player/guild is accused then punished by god-modding.
Look, no matter what side of the fence you're playing on, we can all agree that DMs do not make a Guild great. Players, on the one hand, make a Guild exist, and are the blood and bones of the body, the Guild/faction itself. DMs, on the other hand, are the fulcrums for the Guild's ability to exist in the Game Environment, in terms of how role-play is conducted with the NPCs and mobs of that World. This is latter aspect is undeniable!
Yes, a Guild/Faction can surely exist purely on the merits, actions and WILL of the Players in it. But THAT is also RP in a Bubble, if you were to ask me. I mean, do I want to RP my dwarf inside of Kraak Helzak all day, waiting for other Players to come by and pull my dwarf's beard?!? Ha, sucker, that ain't gonna happen cause my dwarf has no beard!

Tricked ya!!
But seriously, Guilds are supposed to have a greater function in the culture of a Server, are they not? Otherwise, really...what is their point? Why build up a Guild/Faction if it CANNOT get involved directly in what goes on in the Grand Realm? And THAT is what ONLY THE DMs CAN PROVIDE. Unless the DM Team is unofficially saying: "Godmod to your hearts delight as long as it doesn't bother others...."
So...how about greater DM/Guild partnerships? Sounds great, yes? DMs, tell us guild "leaders" what you need from us to help you! Approach us with developments in the IG landscape, and give us a chance to respond as a Guild Unit, and make the effort to be a part of the Lore of the Sword Coast! Don't abandon the Guilds to "make the first step."
This isn't rocket science, you know? It is really all about willingness and interest. And, communication. So, if there is no willingness and no interest, at least communicate THAT, so Guilds know what their true possibilities are. Thank you!
