I apologize if I created the topic in the wrong place; if the moderation deems it important, they will move it.
However, I ask that you provide an argument for your answer, as I need 100% accurate information to defeat the Sylvan faction.
In fact, you shouldn't expect a lot of answers – for example, I don't know a 100% guaranteed way to defeat the light elves. ;)
However, you can read some things here, and there is also some information about fighting the elves here...
