Water doesn't magically disappear when you hit it with a rock or air. It doesn't fully evaporate either with fire blasts and unless its fully dispersed by air currents, water can be gathered once again. It makes complete sense for it to restore after moving it around.
Jedcore implements durability in some abilities.
This plugin needs to think of more than just what's canon. They need to also consider what's balanced for players.
Configs are there, so servers decide what to do with it independently, the devs work on the default balance. Theres no need to use balancing as an excuse for an argument, all we can do is suggest.
Neither does the lifted wall of water bent that's twice the size of a bender. Actually water shield breaks immediately after absorbing the attacks or after being stretched, so really what's the point of bringing up canon argument when the one we have in-game isn't even accurate. Either the ability must be fully canon (reworked to how it actually canon is without Num's suggestion) or non canon (the way it is and with Num's suggestion) If we gonna bring up "But this isn't canon/far-fetched" as a determing base.
Actually it makes complete sense for it to be double size of the bender, it
actually should be even bigger. You can look at multiple bending fights or even just katara or benders traveling underwater and they bend way more masses than the surge shield, one off the top of my head is the
HEALING master vs Ming Hua atop the airbending temple, both sides using huge amounts of water.
I've said this before, the plugin is heavily canon based, all abilities can be found in the avatar world and surge is one of them.
This is true but you could only get stuck so many times before you can’t hold it anymore. Surge let’s you hold the shield indefinitely not taking into account physical exhaustion
Placing a blob of water in front of you should be one of the less exhaustive things, could probably stand there for hours. I think some type of chargeable surge would be a better concept, it would be limited to current water and would increase the longer you hold shift but it would still increase insanely fast and this could turn into a config option. And it could decrease when hit(would still be kinda irrelevant since it should charge fast).
A quick phasechange/surge wall combo that would allow placing permanent ice walls(still melt and can be mined) would be
cool.
