I have a scenario for you and you tell me what i actually HAD to do.
Lets say I go down to the lower lvl of garlaige citadel (where serket spawns) No one is in the area but meh so I start killing off chamber beetles for whatever reason (lets say skill ups) Now after about 30mins or so of me doing this an exp party shows up and ask me to leave/stop killing mobs because theyre trying to lvl. Now me being in a rare generous mood I do so. Howveer my question is did i HAVE too? Seeing as i was there first plus if youre skilling up weapons youre kills are pretty slow so if you taking 5-10mins to kill one mob is intereferring with a parties exp they need serious help.
Also usually if another exp party comes in and start camping on top of your current party then party that is camping on you usually has to leave because you and your party were there first so if that rule applies for two exp parties does it also apply for someone skilling up there first and another party decides to show up I mean Id think I was here first so if you have a problem with that you can either deal with it or leave? If not why?
