Fully agreed, including that Athletics jumping is the core case, because of how it interacts with the movement rules, which are themselves fundamental to 4e's combat resolution framework.On the second issue: I don't fully know how to address this either. I expressed it in terms of the Athletics Jump ability. In combat this is a move action governed by precise rules which generate a distance covered. While these distances naturally grow to fairly fantastical values (high Epic PCs might jump 60' or more, far beyond the 29' outer limits of mundane human performance) they're still not really in keeping with everyone's view of the fantastic nature of almost-godlike level 30 characters (IE they can be actual demigods). Outside of the realm of combat it is quite easy to simply formulate the game in terms of narrative and what sort of fiction will fit with the desired tone, but its hard to see that as a very good approach IN combat.
This is interesting. If you've mentioned this before I've forgotten it, but reading it now I'm intrigued!One approach, inspired by my reading of the litrpg Age of Adepts where there is extreme scaling, would be to actually scale the tactical combat spaces.
However this is not really addressing the underlying issue, just kind of attempting to converge the two paradigms a bit in terms of what they actually represent.
It also actually solves another problem, that swarms can't hold enough members at higher tiers within a 1 sq = 5' paradigm. For instance, in that paradigm, a 4x4 Hobgoblin phalanx is only 16 squares, which even allowing for 2 to 4 Hobgoblins per square is only 50-ish soldiers.
If each of those squares was 25 times bigger, then we'd be talking a serious phalanx! Even a 1x1 phalanx could be in the order of 100 soldiers.
This doesn't appeal as much.I guess another approach would be to simply relax combat a bit in terms of stuff like that and just say "well, we will just set a DC to make that jump", though its still hard in that case to portray really gonzo epic action on the 5'/square 4e scale.
In practice, I've tended to find that big spaces with (say) 20+ by 20+ squares tend to do the job.4e Epic battles actually can be a bit tricky to stage in an appropriately impressive way.
The Glacial Rift from G2 was pretty epic! (I photocopied it and blew it up, sticking to the 1 sq = 10' and thus equals two normal squares.)
If you can fit whole groups of giants, multiple hydras, etc on your map then I think it works. I don't think I used many 10' square rooms at epic tier!
