| Or you can design your game without factions. Guilds and alliances are enough, you don't need artificial "sides", that only leads to issues. You just make a FFA world, and it autobalances itself, to a certain extent. At least the old times pvp mmos I played were like that, UO had "sides" but they weren't solid limits, you could switch overnight if you wanted, AC only had guilds(or monarchies as they were called), and it balanced itself, even though I'll admit at some point Blood was too big.
Last solution is add another side. 3sides makes it easier to balance than 2. That's the main mistake mythic made with WAR compared to daoc. While daoc had balance issues, it was still hard for one side to dominate another because of the 3rd which would take advantage of it. So the bigger sides usually had to fight on 2 fronts. WAR went the wow way, and it was a failure the very moment they decided to go 2 sides instead of 3 or 0.
If you decided to do 2sides, no amount of fixes, bonuses and whatever else will help to be honest. Some servers will definitely be imbalanced. And then those servers will become deserted(because it blows being on the lower side for most but the hardcore pvper, and even then it blows). |
