I question the decision to put two conflicting mods in the same pack like that at all, at least for SMP. That is the reason that you can't literally just throw every mod you find into a modpack for server use.It also puts packmakers, especially those managing servers in the position of being forced to choose between either ditching one of the two mods to curb player power differences, or allowing their economy to tank because of the huge power discrepancies.
