Re: Javelin throwing units
 

Generally speaking the difference between LI javlineers and heavy infantry is 3-5 gold and some resources. I will occasionally use LI javs to expand (Ctis, etc), but the units are going suffer heavy casualties against almost anything. Such units in my experience are best not used unless absolutely required for early expansion, as they are not very cost-efficient when you consider their casualty rate. If you like javs, go with Ermor/Py and mass them... most other races don't do it well enough.
