It's a shorthand for Conjure X. All of the conjuration spells in the PHB have the exact same duration: 1 hour. I could write "elemental/fey/minor elemental/animal" and it wouldn't change anything except adding more letters.
No. It would add clarity. Please don't presume others are knowledgeable about your home abbreviations.
So that it lasts long enough to finish casting, obviously. Because otherwise your conjured elemental/fey/minor elemental/animal would disappear before you could finish casting the spell.
I would have been much preferred if the rules made it clear this was the case.
It is the designers job to make this clear. Having to rely on you as a self-professed authority is a poor substitute indeed.
Because 5E never had any other "half of the spell". 5E is a game. It's related to other games such as AD&D, 3E, 4E, etc., but it's a different game. I could spend a lot of time moaning about how 5E has "nerfed" a lot of spells like Magic Jar and Polymorph relative to AD&D; I could research 3E and 4E so that I could moan about how Planar Binding works in those games and how 5E's version is different from those games; but what would be the point? Those games still exist. If you like 5E better; play it. If you don't, don't. If you need to tweak 5E first to make it more fun for you, do so.
Cut the crap Hemlock.
We are both well aware 5E is a game built on several previous editions. Asking the designers to learn from past mistakes but also to rely on past successes is definitely not too much to ask.
The fact is: they had invented this particular wheel already. Yet somebody went ahead and invented a new half-wheel. That is inarguably what we in the trade call "a mistake".
Why do you insist on letting the designers off the hook, when the natural conclusion is to simply say "they messed up". We still need to move on. We still need to tweak the game. Accepting the designers meesed up doesn't mean we're evil. If anything, it just proves the designers are human too. What particularly irks me, however, is the unfathomable unwillingness for some posters to concede they're playing a less than perfect game...
Why not simply admit they left a mess for us individual DMs to clean up? And a rather small one, at that. After all, that's all I'm asking. It's not that I'm trying to get people like you and others to agree WotC are baby-eating devil-worshippers, for Chris' sake...!
I don't know any DMs who are big enough jerks to actually pull the jerk move discussed previously.
I wasn't talking about jerk DMs. In fact, I specifically would like to ask you to stop talking about DMs as jerks.
When I said it isn't the fault of DMs that WotC left this mess, I meant that DMs can and will naturally rule differently at their tables, since WotC left them with no other option. Some of them will allow the interaction, some of them won't. It doesn't make them into jerks.
Don't stamp some of those rulings as jerk DM rulings, Hemlock. If anything here is a jerk move to do, it's if you insist on shaming DMs just dealing with the mess WotC left behind in a different way than the one you approve!
