World of warcraft is not a example for nothing, there is a lot of bots in and a auto-detection dont solve anything, people just bot as usual and if u get a ban u can buy another account and continuous to do the same thing. Tree of savior will be f2p totaly diferente IMC cant profit with the system like blizzard. Blizzard system didnt prevent bots or RMT , just profit with that.
If implementing a captch helps with bot problem, this shoud be implemented.
