Others wanna skip to the end, so they spend 3 days camping raccoons, and then complain that they have to spend so much time killing raccoons. -_-
We shouldn't condemn people for wanting to grind a skill. The complaint isn't that they have to use it on raccoons, its that the training isn't as hard as CP training. They traded hard skill training for monotonous skill training. I don't think the fault is at the people who want to work on their skills.
I think they should change the overall aspect of Hazy Smokescreen to make players immune to attack when inside it and obviously put some aftereffect that prevents players from benefiting another one, rather than lower defense. It makes a lot more sense and we already have enough defense piercing skills.
Also the targeting mechanics of Charging Shuriken and Shadow Assault should be easier and Shadow Assault should be an AoE and not Single Target. SA feels like more of a Wind Blast, really.
As someone who has used the skillsets, I disagree with all of that except Charging Shuriken's targetability. Shadow Assault is already fine as it is, I don't think it needs any changes. Hazy Smokescreen shouldn't give you invulnerability, that doesn't sound balanced at all even if it was a 1-second AoE invulnerability. It's already bad enough that skills have invulnerability frames.
What Smokescreen needs is its AoE more clearly defined (its hard to tell where the screen starts and ends right now) and a protection debuff rather than a defense buff.
Like a single charge is practically a slightly stronger Windmill, give that like a 20 second cooldown or something. Every extra charge adds another 20 with a total of 300 seconds cooldown at 15 charges.
The idea of an increasing cooldown is a good idea. But I think it shouldn't be +20 per charge, a scaling cooldown would be better.
