As long as people join the game and drop a grand or 2 within the first 2 months NOTHING will change. There is absolutely no reason to drop the price if people pay 200-500 bucks for 1 character anyway. People see something they like > they buy it. There are enough of casual players who bought partners or zanpakutos for 20k gold back in the day that are barely online or never join ES / Ryoka. Hell, most of them don't even know how to play. Hardcore bleach fans I guess..
Even if the price is 50k gold for a partner the next event they will put it up for 45k with a few better side rewards. If people don't get it now they will surely get it next time.
The only way to get somewhere is to boycott them.
Not to OP but in general: Behaving like a moron like most of us here on the forums do won't get you anyway either.
