Lich has a very serious Bug

When the number of monsters is at a high level, Lich's use of Essence Drain+Contagion+Decaying Hex+Dark Effigy and other series of combination skills will be judged as using too many commands in a short period of time, and thus kicked out of the server, and it will be reset to a few minutes ago, Lich is a very detrimental experience!

yuup, theres many post saying the same but havent seen a single response from GGG, having same issue :/
