A mass of lancers doesn't really die to halbs, they plow through them like paladins do (ultimately you might have to do some sort of transition against them though, Mongols have great scorps)Incas and goths I can see (but you're still gonna get wrecked by halbs?)
... why? Mongol Heavy Camels are awful, Elite Steppe Lancers will do pretty much every job better even vs Berber Heavy Camels (I've tested this vs a real player, if you can get a nice stack in between buildings or up against a woodline, it's over for the camels), and they have more pierce armor (and 1 range) so they'll be better vs Elite Camel Archers too (Mongol Heavy Camels die in 10 hits whereas Mongol Elite Steppe Lancers die in 12 hits). If you go for camels then the Berber player just mirrors you and you're ****ed.I'd much rather have camel vs berbers
Heavy Camel dies to literally anything that is not cavalier/light cav. Elite Steppe Lancer kills both Cavalier and Elite Serjeant and can do okay vs halb too (and with the +1 pierce armor they shouldn't do too badly vs Arbalests either).Not sure what they give you vs sicilians? If it's an anti-cavalier play... why not camel?
I suppose the best composition would simply be Elite Mangudai + Onager, but it might be easier to do Elite Steppe Lancer/Hussar + Onager/Heavy Scorpionvs Viet wouldn't you much rather have onager or siege ram?
