People said the same exact thing about arenas when they first came out in TBC, time to move along and let something else take the spotlight, I'm sick to death of arenas after one decade of doing it.
Time to have something new, fresh and exciting to do for PvP that'd involve the whole community instead of just the 70k players that we currently have queuing for 3s on the arena ladders.
There is no reason why we shouldn't change the PvP from being focused on arenas to being focused on something new, people don't like it? There is always something else they can play to get their arena fix from.
This game wasn't meant to be confined to a simple 3v3 format for a decade, it was meant to have it's entire world utilized and explored by sociable players who worked together to achieve a common goal. It's like I've already said before, the original developers never developed any of the mechanics, abilities, map designs or character animations/movements for an Esport ready game for such a small and confined room with only a maximum of 6 players. They never knew that in the future that an Esport competition would arise and that their game would have to rapidly adapt to it, and with that came the hamfisted attempt at creating a poor example of a MOBAesque style arena map and slapping resilience all over the PvP gear.
That in my opinion was a terrible way to go about creating a new format for arenas and because of this, arenas has never truly been balanced for decades, all comps will have a certain comp they CANNOT beat, no matter how much time and skill the dedicate to it, no matter how well they play or utilize different techniques or tactics, it simply won't work because changing the abilities and mechanics would require screwing around with PvE stuff and we all know that PvE players go into a complete tantrum if we do, remember what happened when the legendary cloak in MOP required 2 BG wins? Lol.
The majority/minority argument is a terrible argument when the "majority" of players don't feel involved in the community, don't feel involved in the game and just do it for that one certain PvP mode called arenas, that isn't the community that represents WoW and they have no loyalty to this game and will quickly switch to a newer game if it's superior to the arenas game mode. Veteran players who've been playing for as long as I have are more loyal and have stuck with them through thick and thin no matter what because we care about the game for what it is.
Notice how quickly subscribers have dropped up and down in the space of a few months compared to how subscribers dropped during the period between 2012 - 2015? That's a representative of how little the newer players who joined this game recently have invested into this game and that they're willing to drop the game immediately after experiencing something they do not like. And now if you notice the period between 2005 - mid 2011, you can see that there aren't that many sudden spikes in the numbers as it goes up or down and there's actually no downs at all, just a constant incline of subscribers because they enjoyed the content and they never felt the need to quit.
And that counts for both PvP and PvE obviously but then you have to notice something, the arena PvP participation during the period from MOP all the way to Legion has dwindled and there is a forum post showing statistics and explaining in depth as to why this is happening and some of the points I raised have been pointed out in this thread as well:
https://us.battle.net/forums/en/wow/topic/20752538520
Furthermore it means that while the PvP participation is dwindling, less resources are being spent into keeping it alive and instead are diverted into PvE, hence the reason why we've been seeing positive outcomes in PvE and not in PvP, one look at the first page of any arena forum in the world will speak thousands of words on the state of PvP in general and that isn't only restricted to arena but every other aspect as well.
In conclusion I believe that the only way to get ourselves out of this slump is to somehow create a new PvP mode or reuse an old existing PvP mode to entice the entire community of WoW that includes the PvE/RP/farming or grinding communities as well into taking part and increasing our numbers in PvP participation, people are clearly getting bored of arenas or are getting angry because of PvP imbalance due to PvE designers/class designers not taking notice of PvP consequences of their actions due to the fact that people are beginning to care less about PvP and more about other areas like I've said already.
Which is why I've suggested the ideas that I've suggested in the original post.
