It is an option for more pt invite, if you want to try it then just try it, or just don't and accept the fact that there are less pt invite option. I'm not a native JP speaker(in fact I'm not even a native English speaker, but that's another story), but I play on JP timezone most of the time, in both FFXI and FFXIV ARR. How else do you expect me to get a party? Bitch on the forum? Sit in town and camp for English /shout? I just make a list of frequently used JP dialogue and try to solve the problem.
Back in June/July 2013 when people do delve as a LS before skill update because delve was real hard, I was in JPLS clearing delve1 with JP. When I play ARR in Sept 2013, I also did endgame event such as Coil with my JPLS. Those events are 10x harder than skirmish, requires even higher lv of communication. I also occasionally join JP /shout in both XI and XIV. I don't really understand what's so /facepalm about it.
Anyways, my point is. If the lack of /shout is an issue, there are other ways to solve it. Further more, there WERE English /shout in that SS and apparently that VW /shout is accepting English players, or else he/she wouldn't /shout the NM name in English. You guys all completely freak out about the idea of joining JP pt and ignored the fact that there are also quite a lot of English /shout still exist, just not as many as JP /shout. Tumz complained about the lack of skirmish 3 English /shout, I saw one yesterday around 2am pacific.
If the idea of "You can try to join JP pt if there are no English /shout" is /facepalm, "English /shout doesn't exist" is certainly a bigger /facepalm. It's not even the fact.
