In most other MMOs i can leave a skill off the bar if i do not find it useful.
But with the weapon oriented system that GW2 has, i am left with having to ignore it sitting there on the bar.
I would much rather see each skill slot have variations on its theme that change up how it behaves.
This way you get the same overall theme, but still allow the player to adapt a profession to his way of playing.
Take skills that knock back a opponent. All fine in SPVP and WVW, but pointless in PVE. This because mobs can’t fall to their death. If they hit a ledge, they simply stop. So why not allow us to swap it for one that knock them down instead? would make no practical difference, except we no longer have to chase them around whenever they go flying (and we would no longer kitten of melee fighters in group events).
Or a more direct example, Engineer pistol #5 (Glue Shot). The only thing it does it leave a AOE cripple field. I would love for the option to swap this to something like a acid pool DOT.
