Dysfunctional Rules IV- It's like a sandwich made of RAW failure!

[TuggyNE]

So you are saying that a creature flapping its wings while jumping has no effect?

No indeed, but if you're flying, you're no longer jumping: you fall differently, no longer follow any standard trajectory, and are not limited by Jump check results in height ascended or distance covered. However, you are limited by flight maneuverability in ways that may be more restrictive than jumping.

Again after using its standard action a creature with wings (60 ft fly speed) and 30ft speed moves 20 ft and jumps 20 ft. This creature is supposed to move in the same way as the creature above without aid from its wings?

I would preferably model this as simply switching from land movement to flight, with no Jump check at all. What difference would it make, after all? When flying, you touch down where and when you wish to. (The resolution of the rules is too coarse to really cover things like jumping off into flight as anything more than "OK, you start flying".)

How about creatures with wingless flight?

The same as winged creatures, but more so; it's obvious that running starts and leaping simply doesn't make any difference to their flight effectiveness at all, and the Jump is entirely unrelated.
