My suggestion will get bombarded by "it's already implemented in a way", "then why do we have BG?", etc. etc.. I'll just say it first, it's just a suggestion, it came late, i'm saying it now. So say what you will, if you like it or not and please give an explanation, i don't see a post just saying "No" or "Yes". Now on to the suggestion.
Since lots of people are frustrated/mad/disappointed/sad, all around butthurt that the GM team chose to implement KvM and not Flavius or Terra Gorge. Then i thought about who some people actually loved the idea of random teams duking it out, myself included. So since heRO is all about customization and adapting iRO stuff to our frail little player base. Then why not make KvM into a normal PvP room? I know, I know, its A LOT to ask, maybe... Anyway, have one PvP room called "Team PvP" or something, when a player gets in, he will spawn in one of two sides, like in KvM, then he just goes to kill the other group with his group, the map will put the player in the side with the least numbers. I know there will be problems with the whole "who will the players avoid damaging their own side without a party?", tell you the truth, i have no clue. Since i don't think there is a way to actually make them be able to avoid each other like guilds do in WoE/GvG. So, if there was a way to get around that, then it wouldn't be a bad idea to try.
Now to the other question "Then what will happen to BG?". Well, GMs have the final word on everything, but i would say, keep it, add Flavius and Terra Gorge and leave KvM. That way people that were all punctual and stacked up their points still have a chance at the KvM equipment, and still have their E-Penis erect by having their names on the leader board.
So yeah... That's about it, thanks for reading
