sorry about that, i did mean 4 options. when i said greek heroes i also meant that fortress unit (hetaroi, gastrophetes, myrmiden with its slaying upgrade which increases its damage done to myth units).
for the number, i meant for example 50 units of each:
50 herser or 50 atlantian heroes or 50 priests etc. Or whatever number, as long its the same for all options.
when i said army options, i meant that a whole army composed of that unit, so only loki hersers for first option. for greek it's the four heroes and the fortress unit.
Also, i didnt know that siege units have bonus towards myth units.... so for the purpose of this "poll question" answer with one of the four options, i just wanted to know what kind of army players preffered to fight a titan from the options that i listed. I wasn't really refering to whether the map was supremecy or whatever, because in the end it doesnt really matter does it? it wont affect what you would want your army to be composed of.
Finally, assume that the oponents titan is on it's own. i.e. no other units.
i hope this has clarified the question, and please ask if their is anything else that needs more clarification.
