My campaign is dominated by one faction. The other factions have very few players that still participate. I play for an underdog faction.
Previously if we had a strong group of 12 (or more) we could take keeps and resources quickly before the enemy zerg arrived. This kept the campaign fun and interesting even though our faction was dominated. Now with the NPC buff the enemy doesn't even have to show up.
NPC mages kill v12 players in 3 shots. Players under 50 are completely useless against them. Small scale sieges are utterly pointless. Over the past few days our faction has become even more demoralized. We can punch holes in the wall, fight off the defenders and then move to the flag only to wipe repeatedly to the NPCs.
Even when we take a flag by the time we start moving to the next, the NPCs start to respawn. Cyrodiil is not supposed to be about PVE. If the enemy has been repelled a keep should not be defended by NPCs alone.
If the intention is that groups under a certain size/level should not be able to take keeps, Zenimax needs to publish this information so we don't waste our time. Since the patch keeps have sat open and undefended with holes in the wall defended only by NPCs but the underdog faction could not take them.
