There are lots of maps, where you can use this megajump, even on bumpers to gain speed and/or height ..
in contrast the grappling hook is unnecessary, - most spots can be reached by laser jumps as well.
still there are quite a lot maps, on which such high 'camping spots' can spoil gameplay..
which takes me to the point:
at first of course MORE maps would be fine..
including some useful ones for tournament play - means, that the map-maker is in contact to some experienced gamer, who can show potentially bad habits on the map.
to explain, i think of quake 3 arena - where (in my opinion) most of the avaible spots reachable via rocketjumps are designed to be such..
in Nexuiz it's more an exploit than a feature.
