JCUP
I believe the rumors about JCup stemmed from a livestream where Jmod Ayiza let known of the interest that Jagex was planning to run a JCup. Personally I wasn't too confident as Jagex had routinely let the clanning community down time after time and the fact that Ayiza just rejoined Jagex. However recent activity in the main CWA scene showed that many members are taking this seriously, thus I decided to ping Jagex Ash on twitter myself and I received a beautiful answer:
In light of this confirmation from a senior developer in Jagex, We believe that many clans would probably want to conduct more CWA events to prepare for JCup
Sharkbrew will be supporting your efforts by using our sponsorship money to fund more tournaments and activity-based CWA events so that even weaker clans can be rewarded for their contribution towards the overall activity in the CWA community.
Stay tuned for more updates!
