Well, the weakness of onagers are mainly cavalry and other onagers.
Halberdiers are the most common "escort" because they're the cheapest way to deal with hostile cavalry. And if they die under against other onager fire, it's not such a huge loss.
If you're really rich, mamelukes and mangudai also make great escorts.
I feel that pikes escorting is a bi prblm because theyl be abit behind and cav will kill many SO till dead by pikes. I tried micro Trebs vs SO ( when i was aztecs and had no other option) but this didnt work vs korea SO + Unique scorps.Well, the weakness of onagers are mainly cavalry and other onagers.
