I can add a bit of info here but tagging /u/anet_karlmclain in case he has anything to add.
sword scaling - known issue on our radar. it's a tech issue of firing skills in different ways in the back end. The damage will have to be looked at and adjusted once this is fixed.
sword 2 targets - this is a known issue that needs some new tech to resolve but we know about it and it's on our radar to fix.
jalis hammers - on just inclines? it shouldn't end unless you run out of energy, turn it off or the projectiles hit walls. The projectiles should be hovering above the ground so they should follow the terrain of inclines.
uw legends - we know right now there aren't many options. The work has to be weighed against other things we are working on but we'd like to eventually make more legends useable underwater.
