from ToS INA Developer Q&A Translated
Q: How many large scale PvP like guild wars will be available? We want to know about these informations as well. Or maybe, will there be a Server vs Server, or Castle War, or other types of PvP as well?
A: We are still discussing about this topic. Guild vs Guild to fight over a territory, or maybe a field war. Whatever it will be, IMC Team is still discussing about it
alright IMC why don’t you just call it Colony War already. Given that WoE is property of Gravity, IMC cannot copy the feature. Although they can re-implement another castle siege type of content.
However IMC had made their guild war event in GE which is Colony Wars.
This involves individual guilds fighting across the world map fields to control territories via capturing colonies(Emperium in RO terms). The more territories won the more cash reward and bonus guild buffs are earned.
Also bragfest about the number of territories you guild can captured that will appear in the world map.
Majority of Events happen on Channel 1 so during Guild War event, farmers should avoid channel 1 since its a war zone every where.
