Since we keep hearing the War College mentioned. And Gerry Duggan responded to my tweet:

"Do you think the main X-men mentoring some of the younger X-men that can be viable X-men is something you can see working or would it be too many characters to juggle?"

With this response:

"I think Scott & Jean are here to make sure the next generation get seasoned, while also learning from them, too. Synch has more XP than the two of them combined. There’s a run idea simmering about how your question might be answered elsewhere, too"

Obviously I am biased towards the Academy kids getting more screen time. But if I were to see a War College series I would love to see them using that battle island more often for training and going on adventures and taking down villains like the CoH or Purifiers or Sapien League. And most important getting trained by the seasoned X-Men

Wind Dancer with Storm
Hellion with Jean or Rachel or Exodus
Mercury with Random or
Anole with Nightcrawler
Rockslide with Colossus
Surge with Northstar or Quicksilver or Storm

Etc
