It was a reflex of mankind, some people trying their best to achieve something others having fun destroying their efforts.
Boss is doable but Republic players ruined all tries. Don't get me wrong its a PvP server and therefore they are completely entitled to do so, but after so many tries it stopped being world PvP and just being griefing.
It's actually sad that on a Friday night the best thing some players have to spend their time is to destroy other people goals.
Because destroying other people's goals is fun. Get over it.
