there are some really good ones from Cash Shop
I don't know when did you start this game, but Physical Shadow Set in the beginning was a box costed 1800 KP
And Vana/Rideword Hat are basic gears for a lot of ppl.
Plus Peco hairband, Robo eyes and this and that.
Even peco peco has drawbacks, faws not much for example, when you have an item that is best in slot with no drawbacks and sold at cash shop, then i dont see it as positive. Actually i dont even think that is good that cash ítems became the normal thing to wear. (Im talking about cash shop exclusives)
Also im pretty sure even if you can get ítems in-game and also in cash shop, there will be people who Will bought it from cash shop because covenience, wich is kind of ok i guess, as long as the game cater to both audiences, ive been playing this game for long time and i knew a lot of people who Will use money to speed up The experience, i mean thats the whole atractive about vip wich i think is fine because just speed up a process that can be achieved at a slower pace by normal means. (And not everyone have the time) The situation is completely different on the gear stuff and when the game make some things that are virtually not possible unless you buy specific cash shop items,like having 100 mdef pierce (right now can be achieved with a pretty los chance on rng after 16.1 was implemented with the vicious mind weapons), or The chb case.
Anyway im not fighting with anyone here, im just stating some things i genuinely think about how this game has turn, i myself used to bought vip very regularly and i like The convenience stuff cash shop bring, like inventory space, less weight blues and stuff like that, i also spend some on costume stuff, i remember i bought a lot of The first costumes they implement (still have those, when they Say costumes Will be that, only cosmetic stuff) at that time you can buy gear from cash shop, lol a CK wich can be farmed aswell, and i know people who actually Rent those gears, go figure hahahaha xD
