Define "useless". EB is not about the gameplay, but the historical accuracy. The unit may stink, but as long as it is important for its region, and possibly filling a regional slot, then it's in EB. True, some units are somewhat redundant, and in gameplay terms, useless, but just because Thorakitai are better than Thureophoroi, who consequently seem useless and redundant, does not mean that Thureophoroi should be taken out. Nor does it mean that Thorakitai Hoplitai (Greek Heavy Hoplite Phalanx), which are quite useless, should be taken out as well. Overall, KH has numerous redundant hoplite units, as the nomads have redundant cavalry units, but one cannot simply fill unit slots with something that is more useful and exciting than historically accurate.
