BTB game type rotation

Got a small beef with big team. Love the maps for the most part but the game type rotation is just terrible. I feel like it only selects slayer variant about 15% of the time. I feel like almost every match i play in a sitting consists of 3 games of CTF and then a match or two of territories and then a rare match of slayer. I used to think it was randomized but iv’e been playing it too long now to know that’s BS. 343 if you would so kindly up the amount of slayer in big team that would be cool. You know, so i don’t get bored of the only mode in halo 5 i find enjoyable? Thanks.
