This would promote a lot more the gameplay. I have 5 active friends and we don't wanna to play splitted. We want to play League all together. 6 players online would be very good. But at least allow 5 players.

A good way to improve multiplayer it's this:

Example 40 monsters suffer from different debuffs / damage / calculations. This is bad optimization.

The ideal and future for the industry it would be pack of mobs be debuffed and calculated like just one monster. Example: Each 4~12 pack of monster walking together in the player screen they suffer from same debuffs / damage / damage aplifier / damage ilment / etc. So to make different packs just change their collor so player will know which pack it needs to debuff etc.

Does it optimize the game ? Yes. How ? Imagine 30 monsters and 4 players using 4 different skills each, we have 30x4x4 different possible calculations. With the pack idea it would be 1x4x4. See the difference ? I hope you implement so you can allow 5-6 players together. Thank you.
