First lets list some stats.
I will be giving comments along the way.
I used the tool for these stats but you probably already know these already.
ATK per cost: Rank 8/15
Worst attack unit in the game in this aspect. It is even beaten by a leggionaire which is a hybrid unit.
ATK per training time: Rank 2/15
ONLY place where EC-s shine. The only unit that beats them is clubswinger.
ATK per crop: 6/15
This is of course without having a LV 20 horse drinking pool. If you have it maxed this unit becomes barely decent by sharing the 3rd place with Equites Imperatoris and axefigther.
DEF INF per cost: 12/15
DEF CAV per cost:8/15
Overall DEF per cost: 11/15
This is what I am most bothered about, the description and picture depicts EC-s as heavily armored units. This is in my opinion a trap for new players who might consider using them as def after reading that description.
They are not good for def. Scrap that one they are not good for anything except depleting your resources faster when you see an incoming attack.
DEF INF per crop: 11/15
DEF CAV per crop: 8/15
Overall DEF per crop: 11/15
Same as what I said above. Dont look at the big number on their def rating and think to yourself they might be good for it. They take 3/4 crop.
Efficiency of stealing resources per cost: 14/15
Their lowest. They are beated by phalanx, spearfighters and druids.
Efficiency per training time: 11/15
Even here they are beated by defensive units. Their raiding ability is abysimally low.
Troop speed:10 Barely outrunning imperians even with horses.
*Why EC-s do not fit Romans:
1. They have real fast training time, Roman units are supposed to take long to build up. So thematically speaking they are only unit out of place.
2. They are outshined by EI-s in every single aspect except one. Their fast training time is only thing they have superior, but without any other uses they are just bigger resource sinks.
3. Even though they have same attack you will always rather want 3 EI-s then 2 EC-s because of way combat system works. 1200 units compared to 800 units will have a bigger horde bonus. IIRC* Add the fact that EI-s are faster, carry more and cost less and EC-s just look like that retarded kid you had in class and had to deal with the entire elementary school. Hell even resource wise EI-s are better since they are not iron heavy like other Roman troops so they help you
balance out your resources better.
4.They dont fit into the Roman end-game fantasy. (Keep in mind that this is just my opinion )
*Ways to make EC-s usefull:
Keep in mind romans are already in a pretty good spot so we dont want to add too much power to their unit, even if it is underused one.
1st proposal: Turn it into a purely defensive unit. Transfer a fair bit of that attack into infantry defense and we might have a thing or 2 we could use it for. That attack is wasted anyways.This buff could look like something like this:
180 Attack-> 60
80 Defence (Infantry)->140
105 Defence (Cavalry)->165
2nd proposal: Increase carrying capacity, speed and redistribute resource cost. (The less invasive approach I would prefer) This would allow EC-s to contend with EI-s. They dont have to beat the EI-s in any of these aspects, but they just need to stop being so bad compared to them. This buff could look like something like this:
Carrying capacity 70->90
Redistribution of resource cost to something more appealing.
Bonus opinion on EC:
Waste of such a cool name.
