Ans asked me to copy paste write about this so here it is.
TM 03: Psyshock
"...it is located too late in the game, especially given how it is later than Psychic and has an obtaining requirement that doesn't match it's usefulness."
Its the reward for completing the dex up to 500 pokemons, I've discussed about this and it could potentially be replaced with:
The unavailable Z Crystals (Excluding Flyinium, its seemingly too overpowered)
Another Life Orb
Another Choice Item (Excluding Scarf, I mean, its obvious)
TM U-turn / Volt Switch
TM Calm Mind
And Psyshock could be move on to:
"Maybe in Neo Reborn somewhere?"
At the bottom of the Devonyx, after the PULSE Magnezone fight
In the employee area (We need to fill that place up with as much items as possible)
Anyways this was mostly what Ans said so, yeah, say any opinions.
