So will it only be for REDSEC and Portal games? If so a waste of time.

Season 5 will brings a normal server browser that we all used on previous Battlefields

Sounds good if that happens, with persistant servers.

Hi there,
Server Browser will launch during Season 5, giving players more choice in how they find and join Battlefield matches, as well as build communities in-game.
We’re focused on addressing pain points players have experienced with Server Browsers in previous Battlefield titles. We’re planning for Official servers to be easy to identify, support full progression, and remain supported by regular matchmaking so active matches can continue to be backfilled. We’re also working toward a more persistent match flow where possible, with the goal of keeping more players together across matches while still respecting individual matchmaking choices.
