Mythic wants to:
Make the 41-50 levels go quicker
Make it easier for wider level ranges to XP
Get people to RvR in places other than Emain
So...G says...
Make the XP bonus for xping in the frontier HUGE. Double, triple? Dunno. My current cap is around 52 million...if I could get that or more by hunting padfoots, ellyls, boggarts...guess what I'd do. And guess what? Hibs and Mids would be out to pop a cap in my ass.
Also, I think keep taking should grant rp's to the takers. My favorite hunting spots are dangerous if Boldiam or Berkstead are in enemy hands. But they wouldn't be in enemy hands long if Albs got RP's for taking them back. Also, it would make it easier for tanks to get RP's. 20 level 50 paladins could take a keep and get RP's. Name something else 20 level 50 pallies could do to get rp's.
I think you should get RPs for killing the lord. Not a lot, make it 1000 RPs divided up among all the people there. God... I'd have a million by now. Maybe double it for retaking a home keep. Plus this would allow tanks to get their first 10k RPs that they need to get the new RSPs that Mythic is using to balance classes.
