If i read the patch notes right, I dont think the keeps actually have more health i think its just that lvl 2 keeps now give the same bonuses as a lvl 5 under the old system. Meaning that the keeps upgrade to full alot faster than before resulting in you being more likely to come across a keep the same strength as a lvl 5 under the old system.

@ZOS_BrianWheeler , alot of large scale players arnt happy with this change though. I know what ya said about being able to see the effects of keep degradation by the time you flip all 3 and get to front door. Problem is large scale doesnt want or do this because your going to have someone spot on the map that the resources are flipping and its gunna get called out in chat. Most large scale groups hated when small scale would do this before the update. Its more true now than ever with keep recall stones, as res locks dont matter. You can go front door, flag it and noone can port in if you were fast. Or you can flag up resources and have an 80 man zerg to deal with.

The change has made it so now both option dramatically increase the chance of dealing with that 80 man zerg. Keep takes longer to flag, more likely to get called out. Flip resources, most definitely gunna get called out and roll up to the door to get smacked because the enemy is gunna port in as they resources flag at different times, even if you spit the group and res lock, there res arnt gunna flip at the same time and they can still port in with recall stones besides that.
