We were all told Play How You Want!! Great idea but it just doesn't work for an MMO. In a single player RPG it is great and allows anyone to enjoy any style they want to play. In an MMO difficulty is set for the server, not individual players. This makes it impossible to balance without set roles. Other games have tried with varying results but almost all end up with more cookie cutter builds than the set roles have.
In ESO you have your class skills, race passives and the ability to mix in any variety you choose of weapon, guild, alliance, world, vampire, werewolf and armor skills and passives. I hate to say it but this will never be balanced. Some races/classes will always synergize better with the other skills/passives you can change at will. There is just no getting around that. The idea of Magicka and Stamina make the balance issue even worse by having certain skills scale with each and certain armor/weapons synergize with each.
As long as all class skills scale with Magicka, which also is buffed and synergizes with Light Armor and is also the resource used by staves you will never find true balance. This doesn't even touch the issue of Stamina being the fuel for all non-staff weapons and also being the resource needed for defense.
You also have the issue of trying to balance PvP and PvE. This game allows skills that are only obtainable through PvP to be used in PvE. Games with structured PvP had a hard enough time trying to balance it but large scale PvP mixed with every class being able to stealth, balancing small scale gank squads and zergs while every change made for PvP changes PvE and vice versa. This is truly a balance nightmare.
Play how you want is a very ambitious idea but it just doesn't work for an MMO. If we want the game to succeed we probably have to abandon the idea of it. No matter what FOTM build is nerfed a new one will pop up, it is just the nature of the beast. There are far too many combinations of skills to ever achieve true balance.
At this point the Devs have to make a difficult decision. Move towards the route of a traditional MMO which has more defined class roles or a never ending series of nerfs, adjustments and changes to content that I don’t believe can ever find true balance.
I'm really not sure what the point of this post is other than to say what I'm thinking I guess. Ok flame away!
