It's not, but one of 4e's core philosophies is that you don't need stats for something you won't fight. In many ways, 4e combat statistics don't exist until that creature is in a fight.
Sure, but as said before, who are you going to fight with those newly earned level 29/30 powers?
You get on level of play with them from 29?
That makes the game only really 29 levels of play and a 30th level to look at.
Several deities are already level 35, so why not have more than just Tiamat and Orcus for higher level play?
This is another "Zen of 4e" thing. Creatures' statistics are not there so creatures can fight each other. They are there so they can fight PCs. In 3e, creature stats are kind of an absolute way they interact with the world; 4e stats are the way they interact with the PCs.
Talking to the wrong one really about 3rd creature stats.
CR/ECL/etc and I never wanted to look from the DM perspective again.
All editions nothing has stats until they are needed by the players to interact with. So the DM should have to create the stats for everything just in case his players will interact with it?
I don't think it's a game designer's job to come up with everything any group of PCs will want to do.
I think it is the game designers job to come up with the rules for dealing with the creatures they created including the deities, at least, in the PHB and setting specific books.
If a group doesn't want to fight Pelor, they don't have to, but what of those who may have a need for their story completion?
Removing the ability to create story elements because of a lack os insight to think someone may want to use something you have built into the foundation of the game as a plot point only furthers the positions that state 4th edition is mostly just a miniature wargame with RPG elements thrown in.
I do think it's a safe bet that, out of the subset of gamers for whom fighting gods is interesting, many more will need statistics for Tiamat than for Pelor.
So it is a popularity contest and not all gamers rights are equal to decide how they may want to create their stories?
I don't think that is right at all and goes with the previous poster saying that WotC in some way seems to be imposing their playstyle and story choices on other players, by not throwing together the other gods so you do have something to do with your level 30 character other than retire him or upgrade those level 25 monsters and play with them again until the end of your story.
It just makes the potential of the game a bit lacking to offer only one side of the cosmology as a probable or likely opponent.
