Sxuz, Many have but, I assume you are looking for an actual response to which an actual question might be better then asking: "Any one tried this?". So, what's your question?
I have it. If you have never played the class you're botting, you're going to have a hard time using Cokx's routines as much of it is manual play using Hotkeys for certain situations. If that's what you're looking for, I would say definitely look into it. I personally love their routines and use them frequently.
i use it and love it personally. i agree it helps if you know about the class before hand tho but even if you dont i wouldnt imagine it would take that long to learn. i only used warrior in arena must say this warrior routine seems really really strong imo and again only IMO but i would say its best warrior routine avaliable for pvp hands down. i used to use richies then tuhana (still use this one for every thing else inc afk bg farming) now its stricktly gladiator suite
