I could say , it not exist .
For example - templar . There is a 2 sets which you want take on main bar which will buff you . War Maiden or Deadly . That's what you will think in first time .
Deadly will give you 15% DMG to channel abylitys and dots - it will buff all your dots , jabs and beam .
War Maiden - 600 SPD WPD (For some reason in game exist this 2 stats which basicly one) to magicka DMG abiltys - like most of plar class dots and jabs + beam .
Sounds nice and relevance to take any of this sets , but no . Looking in raid or dungeons setup you will use only deadly set , because war maiden will boost your damage around 10% .
Like in game so much sets and no variabilty which to use , because most of them like trash . Another example Ophidian Venom and Aegis Caller.
Venom is increase your LA damage every 2 second for 3k (on my char with my stat lines) if target have poison effect on hym .
Aegis caller is procing out 1 LA and deal 3K AOE damage for 10 seconds .
Like one set in focused on your LA and only single target and damage less than easy to proc set , which also deals damage in AOE.
Zenimax , why you not hear any of player to rebalance game ? You don't play your game , cause you have IRL jobe and time to life you also need .
But balance in game in very bed conditions , that's one of reasons why players left game .When you are novice and trying go to raid or PvP - you always have meta and this meta is highly inflict in your DPS . If you have some builds in your mind and trying to make something which will synergys with your class - you have this , bunch of meta sets which is in all DDs same , even not depending on class . Having so strong meta , when every class use same sets , because other sets in compare in absolute garbage it's not fun .
