Just gonna copy past from one of the other guys that wrote it
Features that were available yesterday and have been cut 12 hours ago:
- Cross-region play (the custom game list is no longer global and you can’t play with players from other realms, meaning it’s much harder to find players and fill game lobbies)
- Custom campaigns
- Clans
- Player profiles
- Ladder (ranked matchmaking, stats, automated tournaments)
- Good, [battle.net ](http://battle.net) 1.0 chat system (you can no longer use commands such as /f l, /join; information on how many players are currently playing; list of communal channels; [battle.net ](http://battle.net) news section; overall the chat system lost its’ soul)
- Beautiful UI/menus (in reforged client the menus feel sluggish and less optimised; the chat box overlaps the menus, atmospheric 3D campaign backgrounds are gone, etc.)
- Creative freedom in custom games (the WE EULA has been changed, adding a lot of limitations - everything you create now fully belongs to Blizzard, read more in other topics; censorship in maps and game names, for example a lobby called “booty bay” can not be hosted, even though it’s the name of an offical WC3 map, etc.)
- Classic graphics in Reforged client look worse (shadows are missing, saturation is off, some spells/effects are missing)
- RoC campaign is now using TFT balancing
Features that were available before 2018 and have been cut during the latest updates:
- Arranged teams
- Reconnection via GProxy
- Overall game stability (desyncs or crashes would almost never happen, now custom games are plagued with both)
Bot features (only going to list some of them): - Online lobby list and in-game chat, available from a browser (what games are hosted right now, how many players are in a lobby, etc.)
- Competitive custom games (auto-balance and matchmaking based on ELO or empirical algorithms specialized for each custom map)
- Ability to kick/ban trolls (after the removal of bots they added the ban functionality, but you would have to re-ban the person every session)
- Better ping/latency
- Protection against hacks and maphacks
- Anti-spam protection
- Automatic replay saving and archiving with easy search from a website
- Game/replay archive
- Probably many more things that I can’t recall at this moment
I mean to be fair that is not actualy counting anything inside Reforged since that is just what got stripped from the old version but if you want i can find more in a few minutes of searching at most
O and a Edit the list comes from the user Bakker from this (Reforged is a forced downgrade for classic users) post
i do hope he does not mind me copying it
