Pretty self-explanatory, Bedwars duos is quite annoying if you tend to solo q a lot. You can get bad teammates who do not know how to play or people who have very high ping. A solos 8-Player lobby would be a lot better than the 8 Player duos gamemode. 4-Teams 2s gamemodes is just not the way to go imo. I only see 1 or both teammates rush middle for diamond gens. They camps there mid-game for like 5 minutes and don't come off. They gather the best items and become way too overpowered.
When I first played Bedwars, I realised that there was no rewards upon death. For example, 1 player picks up 4 diamonds, I kill that player. And get nothing. I believe it can be easy to implement a feature where you can receive the items the player had on them. It will make the game feel a lot more like bedwars.
Unbreakable Items. Now, this will rarely happen. For people who fight bought swords and armour would've realised the durability goes down. Even if it is completely pointless, making the items unbreakable can make the game feel a bit more bedwars style.
