It's mayhem time. So the die hard pvper's are out and about. Of course event tickets are tied to doing imperial city, battleground's or cyrodiil. PVP should be equal in terms pretty much of skill and gear. This event bring out players who don't PVP or is even geared. Usually you wont see them in PVP, but event tickets is only way to earn them. You get a team of players with like 16k hp and mix match gear, going against geared out PVP monsters, who can one shot up to 25k+ in damage.
This experience isn't fun for the pve player doing battlegrounds for event tickets. Imperial city you go to no cp zone and usually get it done. cyro is about the same. Battlegrounds is the different beast. Mainly my point is if ZOS can make it where pve people can get event tickets during mayhem without doing PVP events. It will save them he frustration of being one shot every time they spawn. PVP players won't get angry at trying to carry a team of pve players to win the game.
This would be like killing 2 birds with 1 stone. I think nobody would fuss if they have a different way to earn events rickets during mayhem without PVP being involved.
