The fact that the under-level-50 campaign is not faction-locked allows players to "exploit" the game.
Recently, I played the under-level-50 campaign on EU PC server for a new, permanent character. I saw some disturbing situations. Implementing an account-wide faction-lock would, perhaps, reduce the occurence of these situations. I have seen these situations also on the North American server.
Examples:
1. Volendrung (the Hammer) spawned behind the EP gate. An AD character swapped to an EP toon and brought the Hammer out to his AD buddies waiting at the gate.
2. AD made an aggressive push to get Emperor for one of their number. After getting Emperor, many changed to EP toons and did another aggressive Emperor push. I saw this back-and-forth multiple times. I know for a fact that guilds organize such Emperor runs for members on the North American server. After getting the Emperor title, most of the faction's players either log-off or swap factions; they do not stick around (with their new Emperor) to retake their scrolls or other keeps.
3. EP was making an Emperor run. 3 EP players on AD toons were working on keeps in advance of the push, taking the keeps, then leaving without doing any repairs (i.e., leaving the doors open). The advancing EP army could then enter the completely-open keep without any sieging required.
4. Frequently players swap back and forth among factions to maximize their AP. I once saw one player (identified by his
@name) swap factions 6 times during the time I was playing, fighting for all three factions at some point.
A faction-lock would prevent a player from using any character on their account to fight for another faction for the duration of the under-level-50 campaign. Currently, players are exploiting this campaign to get the "Emperor" title and to gain AP. Allowing faction-swapping to bring Volendrung to one's home faction is outrageous. Of course, faction-locking would not stop the "professional" players who use multiple accounts to play this campaign as a full-time hobby, but faction-locking would certainly help those players who sincerely wish to experience an honest campaign.
Over three days, I saw nine Emperor-runs (three per faction). (There were more than nine runs in that time, I was only there for nine of them.) For seven of those runs, the new Emperor immediately abdicated (not staying to help retake Scrolls or keeps or outposts or towns), and nearly everyone in the new Emperor's faction logged-off or swapped factions. Only for two runs (out of nine) did the new Emperor continue to play for their faction, retaking scrolls and real estate. Obviously, this campaign is being exploited for the "Emperor" title.
Perhaps ZOS should: (1) eliminate "Emperor" from the under-level-50 campaign; or (2) allow the Emperor skill tree but do not grant the "Emperor" title. That would put a stop to a lot of this nonsense. The "Emperor" title is meaningless when it can be obtained via "exploits." It is also meaningless when a guild will "sell" the Emperor title for a gold donation. Or, perhaps, just eliminate the under-level-50 campaign entirely. Under-level-50 players could then play the no-CP campaign.
