OK, I am still new to PVP as ESO is my first MMO. So, this may actually be in place and I don't know it. I am a primary PVE and RPer learning how to PVP in advance of Imperial City. I know, with the changes coming next week, this may be superfluous. (Fortunately, I have found a great guild to PVP with! Hi guys!)
I have noticed the balance of players appears to be off. There is a big PVP faction, a midsized faction and a smallest faction. The larger two will gang up against the smallest faction before attacking each other. It has even been admitted here on the forums. So, my suggestion to bring some balance in the number of players is to implement a multiplier based on the number of people in the campaign at any given time. Let's say that if faction A is the largest faction on the campaign, then they are worth twice as much AP when they are killed as Faction B. The smallest faction is worth the least AP. So, if someone who is in Faction B and they have a choice between Player X who is in Faction C and Player Y who is in the largest Faction, if they want more AP then it is more profitable for the player to kill the members of the largest Faction instead of the smallest Faction. People in the smallest Faction would get twice the AP when they kill someone from the largest Faction as opposed to the midsized Faction. The people in the largest Faction have the numbers advantage and would get 0.5 AP for going after the smallest Faction. This would entice people in the smallest Faction to play and if one Faction is biggest on Hadarus but smallest on Chillrend, then they would move to the less populous server for their Faction if they want the AP.
