Hi I'm 225 and I've almost never used Kishin to help me level. I've used it a few times but besides that all I've had is EXP coupons. I've been playing for ~3 years now, so my advice is to take the game at your own pace. The game is constantly changing to make things easier, regardless.
How to kill the game 101.
Yeah, except Kishin is such a vital part of the game at this point. Those with no Frenzy Totem or are too poor to buy Frenzy/Kishin service usually make their own kishin mules for increased spawn rates. Kishin is even more vital in Reboot, where Kannas are used by all sorts of people to meso farm.
They need to seriously think out what they're gonna do in place of Kishin, or else they can expect a tidal wave of criticism coming.
Complain is all everyone does. I get that you want this game to be rid of hackers, but when you have tens of thousands of bots running around and only a small force of about 20-30 GMs it's impossible to catch up. Even then they can't make a permanent solution since they'll just keep coming back on a new account.
It's a problem in other games. Runescape, WoW, any other MMORPG you can think of. So the best they can do is to restrict what the botters can do, even when it means restricting normal players.
