Peope getting downfragged for talking about braindead chain jumping soldiers baffles me, it's the most braindead easy way to score points in dm, while effectively not actually training anything but how to bomb unsuspecing players. If you wanna train your dm where it counts, you should do less of that
If you want to be bored and just want easy kills and lots of points just rocket jump incessantly and sync scouts who arent looking at you
Having said that, jumping is an integral prt of soldier gameplay and you shouldnt just waddle around everywhere, use your rocket jumps to be unpredictable or gain advantages in certain head on fights
If you actually want good rockets on people in various situations, both directly fighting you or distracted people (this sort of situation you can't get in mge), then imo rocket jumping is fine if you're just getting to mid or occasionally getting high ground, but you really need to concentrate on your rockets. Going for more directs, thinking more carefully about where you place splash. going for splash on whatever you can think of, the floor, the ceilings, walls, other players or even your teammates.
But if you jump after literally every kill and just chain kills relying solely on the easy hp regen from syncing rockets on unsuspecting players you're honestly wasting your time. Learn to think about placing your rockets, as opposed to throwing them out hoping they hit somebody.
Even worse is if you pussy out of every fight and run after taking 40 damage like zheep said, just another waste of everyone's time, including yours
