Well there are 3 I can think of who would love to have you who are very strong with guild wars and do great numbers with tasks.
First would be:
As you can see they are the top guild and have won Guild Wars all 7 weeks so far. They are a very hard working group who collaborate on ideas for GW success. @Ghaleon would be the one to contact (PSN is Ghaleon)
If they’re requirements are a little high, I also endorse both Nemesis:
@Santandrix runs a great team and they too finish strong in the top 10. (PSN: Santandrix)
Also there’s Quimby:
@Dan_ozzzy189 also leads a great team here with friendly and helpful people who likewise do well in GW each week. (PSN: Dan_ozzzy189)
Both Nemesis and Quimby are very similar all around and you couldn’t go wrong with either.
Honorable mention also goes to to @Graeme and Guild of Gra. He leads a strong guild that usually finishes 2nd in GW. I don’t know what their current requirements are though nor if they’re looking since they had 30 last I saw.
In my opinion, these are the best places someone can end up in on the PS4 if you’re looking for strong, dedicated, high ranking guild’s who are in the top GW bracket and whose leaders go out of their way and lead by example.
