Seriously after 10 years the people dont know how play the JP people?
Here is my personal exp and the time shared with Jp friends.
If you go a Abbysea party with Full Jp guys.
You will be asked for sub /nin if you are a dd. Yes War, Sam, DRK, they want you sub ninja.
If you are a thief/ Ninja / Monk / Puppet they dont see you as DD, they want you Sub dancer for help with the heals
"Kill too fast" Yes your read that good or take much damage is taked as a seriously insult for they.
The 95% of Jp players dont care about parse or damage. They only care about cooperation and teamwork.
So if you go a JP einherjar run. You will notice see all the DDS/Ninja Light DDS/DNC, a lot of bards/whm, cor/whm.
If you are doing a Event with them. They expect you be talk often, if you just want shut up and bash shit, this will be taked as a insult you not are enjoying with they.
They do no think like US. They think in a way more "Fantasy" More DRK use Mp!, Sam tank!, Monk is a light dd will be assist heals!, respect your party do not 1 shoting shit with ukovansara plz ^_^. Oh yeah and more. lol im not surprised they actualy asked for something like this
I SWEAR i saw in WoE spawmeage Drks/whm, drk/rdm, drk/sch jp GUYs casting nukes on WoE Hyper bosses.
