Personally, I feel Competitive WvW is about being the most prepared with the proper classes and gear/ comp / skills, obviously you want to make every class viable in a sense, but the idea that nerfing boons / condis negates any point of solid cooperation and skilled play, if you have 10 people AoE on the same area someone should probably die, its the point of rewarding those who put the time in to make the best of the meta. There will never be an ideal, "all classes can be played with equal amount of utility and purpose" but the need is to ensure there is a spread of classes that enable different aspects of group fighting. I believe many people enjoyed Core WvW fights because they had different aspects, frontline tanks/dps, ranged healers/ glass cannons, a gank squad, it had multiple aspects of play that allowed nearly all classes to have some sort of identity. Current WvW is a mess of Group buffing and tanking that creates either an unkillable dps machine, why would you want anymore than Firebrands Scourges and when Firebrand provides heals buffs, support cc, Scourges provide, Barrier, res, dps ,boon strip AoE Ranged cleave. I believe it is the multi purposeful fact that enables a, who has more players generally wins style of fighting, because it is easy to faceroll your scourge buttons, but when the game is more complex with multiple classes that build off each other is when you find the competitive scene booming and a better fight scene. Core meta was a great example where, Warriors provided CC, immob and some condi clear, while guards provided melee cleave, tank. Backline Eles had to drop waters for Guards to blast and the melee had to protect the necros from being run over by the enemy melee, while now there is next to no necessary interaction between classes because each one can do basically everything by itself. Fixes would start by forcing classes to fill a role they gear for, maybe FB needs to have less overall healing and more boon/condi removal. Making scourge barrier weak unless specifically geared for. Spreading away from the MegaBlob of Heals/Corrupts/DPS allows a more intricate and fun WvW which will allow more classes to fill the hopefully more roles given to players to stay competitive
