This is not a bug, per se, but more of an oddity (hence it's in general--the day I have an actual bug to report, I'll eat my hat).
It doesn't really mean anything in the grand scheme of things, but it does impact me greatly.
What I wanna know is if there have been significant revisions to the rocket splash damage since 1.22. It appears to me that the cross-thrust, errr, the splash in the lateral direction (esp. coming off a wall) has been greatly reduced (follow me? No, I didn't think so.

In fact, it seems to push stronger in the upward direction (z) than before, perhaps exactly as much as it's not pushing sideways (x,y)... maybe the exhaustion model just changed, but the net thrust is the same

To demonstrate what I'm talking about, I've made two demos--yes, call me demo happy. Whatever.
It is now possible to consecutively rocket jump against any flat surface; meaning the sky (and your health) is the limit.
*The 'platformtrain' one really demonstrates the point.
Anyway, maybe only Randy would know, but if anyone has any ideas, please let me know!
