Yes gunslinger seems pretty bad and I just think meterless caltrops stopping run us too advantageous, not broken, but not balanced. Ice clone is an obstacle, it doesn't stop you from running, you just freeze if you run it to. You can run through caltrops, it'll hurt, which is why you take damage over time, but they don't just kill your momentum. You can even do run combos because you're on them. For meter that's cool, but I feel it shouldn't be meterless.You want gunslinger buffed yet you want caltrops nerfed lol. Ice clone makes sense because it has a hitbox that will freeze you if you touch it? Uh...caltrops have a hitbox as well that will stop you from running if you touch it.........I don't know what point you are making there. Can't really comment on the pressure since I don't play Sub Zero.
Not sure what you are getting at with your last point either, yes you can't run through caltrops because NRS says so. Well duh because the NRS developers programmed the caltrops that way because thats how they intended it to work. Its the same with ice clones, the clones don't have some sort of vodoo spell that will freeze you on touch, its because like you said, NRS said so. They programmed the clones to work that way.
