Halo Wars 2 Lag Issues

In recent times, over the past month or so, lag has really become and issue in games. I dont know if 343 Industries flicked off some server switches or messed around with some settings, but its extremely annoying in ranked matches when the game starts of fine then within about 5-6 minutes the game starts to deteriorate and lag and it **gets progressively worse until its literally unplayable**. Leaders/Units dont respond (i.e. they respond like 5 seconds after), Leader Powers either dont deploy on demand on do so late to a point where they are useless (i.e. beams activate way late, teleport doesn't work because the units are dead by the time it activates). I live in Australia, but ping was not an issue for the past 2 years for both me and my friends, we played plenty of ranked matches with no issues whatsoever, but now RANKED matches (And probably other game modes but we play RANKED the most) that LAG to the point of probably the **equivalent of 999 Ping** is the worst. It leaves a most sour taste in the mouth especially when a lot of these matches were quite easily winnable or contestable but instead ends up being a slaughter with our armies essentially "**Standing Still**" while the enemy deploys leader powers and destroys them before they even engage. Im not talking about dropping from matches either, thats another separate issue which while also negative, was bearable due to its rarity but this lag issue is getting to the point where almost 1/5 matches lag like this essentially making it a loss, which sucks when you verse lower ranked players as you lose massive amounts of Rank.
PLEASE LOOK INTO THIS ISSUE.
I know my other friends in Australia are also experiencing this issue so its not MY internet and more likely a form of Server issue.
THIS IS A RECENT ISSUE - For the majority of the last two years the game has been fine ping wise but now problems have started
IS THIS YOU? - Anyone else having this issue? Or is it just me and my friends ironically, If its many of us, perhaps this will be looked into instead of shelved.
THIS IS A FUN GAME - I enjoy playing this game as do my friends, but please look into/fix this, youve had great contact with the community so far, dont let it down now!
Thanks Peeps! Sorry to Rant but I thought this might repair itself over time or be an issue that was only around for a bit…clearly not the case.
