The addon scene is SUBSTANTIALLY more powerful than WoW's at this point and I think that is going to be a problem for these high end contents or people looking for the bleeding edge of challenge but self nerfed that challenge, without self awareness (which is hard for everyone, and imo, rare anyways lol) people will be making the game worse for others because they made it worse for themselves (tale as old as time?). I think the work these addon creators have done is quite interesting and I would not like to punish them, but /honestly/ I strongly believe the game would be better if they had created official addon support that was controlled and then did a bit more to prevent and punish third party use.
SE is in a position of being uneducated, players extremely advantaged with addon use, and ultimately creating the worst kind of content in this situation (DDR). Hilariously non-JPN PUGs still fail this, so you get this really funny situation where because the content is SO DDR you either get quite reasonable (maybe not easy, but like 'normal') if you're in a group of addon using players, and then in a hell hole because the content is 'memorize or fail' if you're not in an addon group (or a legitimately skilled group, not every skilled person is an addon user, but I bet many are). If people are not aware, there are some hilariously good quality addons that will literally draw lines on the ground on what you should do (resolving complex content FOR YOU) in content like ultimate. These addon creators have done a lot of work, so I don't want to demonize it, but it's equal to if not worse than the situation WoW had when DBM was at it's greatest strength.
I believe this makes makes the game more frustrating too, as the addon user is like "its easy you just do these mechanics, that are appearing on my screen on what to do at each moment, usually before they even show up" as they watch the person who is uninformed failing all over. "WHY CANT YOU JUST DO THE MECHANICS". Well they don't have a little voice whispering each step into their ear, is part of the problem (they are not new, and just want you to carry them, is possible still of course).
I just think its a bad situation all around.
IMO, they should 'air gap' (from their network lol) a PC go and tell someone to download and use a boat load of the third party addons, even the ones that come from custom githubs. Make a list of them based on popularity or interesting features, attempt to add any that are reasonable, and then contact the addon creators ask them to create a list of features they would need / like (officially), make that, begin to ask addon creators to move to the official system and start to create ways to catch unofficial addon use and punish it.
