I don’t know what you have done to affect different regions connecting to their local servers but whatever it is is stopping me from playing Halo 5 after midnight.
Yesterday I gave up trying after an hour or so of unsuccessful matchmaking. Tonight I persevered and sat through six hours of failed matchmaking for a grand total of 11 matches. 11 matches in 6 hours!
Prior to the February season starting I could play Halo 5 all night (and often did). That is no longer an option. The changes you have made have effectively stopped me playing the game during the hours I am able to.
It has only been two nights and I am already properly -Yoinked!- off with it.
I’d imagine I’m in a minority of a minority (UK player who plays late nights/early mornings) so I’m not expecting you to hurry and fix this (or even acknowledge my concerns).
I’m posting this to make you aware. Do something about it before the next season starts or you’ll lose more players than just me.
The fact I haven’t seen more posts about this issue suggests it is a localised issue and judging by the posts I have seen it is a European issue. Stop treating Europeans as an afterthought!
