This mod pack has been quite enjoyable to play, and I'm really loving how it has made me finally delve into Thaumcraft like never before, however it is desperately missing two mods:
Bibliocraft: he various shelving, etc., from Bibliocraft adds a lot of useful architectural items, especially for the storage of individual tools, as well as books. It's been a while since I've played with it, but I can't recall there being anything in it that would adversely affect the nature and progression of the Mage Quest theme, such as overly-powerful items or mechanics. As I recall, this mod consists entirely of functional decorations, all of which, as I recall, would be entirely appropriate to the Mage Quest theme.
&
Gravestones: this just plain makes sense, particularly in the context of this mod-pack, if only as an option for the administrators/servers that want it. Our server, for example, is for a handful of adults playing for fun and relaxation. We don't use creative mode, and generally much prefer to work to acquire our mats and for exploration to contain some element of danger, but have had grant access to creative to all the players to enable them to recover from the most drastic and unexpected losses without a lot of grief and heartbreak that might otherwise result in reduced desire to play (please, no irrelevant opinions/comments on player psychology from the peanut gallery, that isn't the point here), particularly when it has been caused by something like lag. Gravestones give players a much better chance at recovering from their losses while not being entirely risk-free, and still wouldn't invalidate items like the various life-saving potions and items, particularly when a server like ours has players who - due to their schedules - are often playing alone the majority of the time, where they cannot call on others for help in salvage.
Just my $0.02: my server admin isn't keen on adding either of these himself because he doesn't want to have to deal with keeping them up-to-date, particularly every time the core mod-pack itself is updated. Apparently I see one of the mod-pack authors has decided that the mod list is now final, but I still feel the need to post this anyway, since frankly the lack of these two mods seems to be a glaring oversight with little to no impact on the actual quests or other mods.
