As long as the game continues to be a grind (of course that won't change, because it is engagement and micro-transactions), people will continue to care most about XP, unlocks, and progression. As long as old XP farms continue to work (who knows why EA acts like they don't condone it, but refuse to take them down), the majority of portal will be that crap. As long as portal continues to be that crap, good portal can't exist. Good portal (the hosted experiences we remember from our past) can't exist because: 1) You can't find good stuff among all the garbage. 2) The good stuff you find usually is empty and requires too many people to start it, or has no progression or unlock XP. 3) The garbage is terribly wasteful of server capacity (1 person wastes 48 or 64 slots per server), and all the portal servers with complex multiplayer run like crap because of it.
What can un-kill portal? Give full progression, full unlocks, and 1 person start to ALL portal servers. If someone can solo start an XP farm and get full everything against 63 bots, there is no other experience as harmful or exploitive in comparison. Don't kill everything else. If you make everything have equal unlock progression and server-start difficulty, you hope that people will start engaging with fun and unique ACTUAL gaming experiences which EA claims they wish players would do more of.
EA clearly doesn't care. They don't listen. They aren't rational.
I have 7 portal experiences I made. They all took a lot of time to make, offer what isn't already in the game (hardcore, TDM, conquest small, etcetera), are an actual game that can be won or lost, are actually challenging and fun, but have no XP or progression. They are exactly the things that people claim they wish the game would be, but no one plays and they are empty. People need to stop pretending that they miss a server browser and miss hosted community experiences, and then do nothing to help keep it alive. Portal is all we have left of that experience; support it and engage with it, or stop complaining.
