Hi Saber/focus, 

I Finished all the 7 ops yesterday with my kill team on lethal and we did have a lot of fun. 

After a bit of adjustment we got the tether mechanic to work just fine, just pick a leader and stick with him, not rocket science.
We enjoyed the massive waves, fighting 3 Licters or 3 Terminators or 3 Ravengers or a mix, was all good fun. We did find that the Tyranid maps had been tuned harder than the Chaos maps, with the Chaos maps just having a few more extreme spawns, but else was just about the same. Tyranid maps, especially TERMINATION had some really great waves with 30+ Majoris with Extrimis thown in there. We hope that you release the AI a bit more on the chaos maps, as those are by far the easiest at the moment. 

Two thoughts 

We would like to see the tether made a little "longer" It only takes a few rolls to get away from each other, and we did find that a bit too game-disturbing, especially if you are in a range-heavy fight. Assault and Vanguards are not something you want to bring anymore and they by definition function outside the tether zone. This will require a rethink from you, so please consider the class implication of the tether. 

Other comments

There are some minor bugs on the new map, especially with weapon selection if you pick up the "tag-gun" for the last boss fight, you can get locked on the weapon unable to change, which is bad for anyone but heavy and Bulwalk (and Assult) 

Last but not least

PLEASE DO NOT NERF ANY OF THIS. Do not listen to the cry babies and low-skilled people. 

The maps are doable, and fun. And the babies will still have ruthless to get all their shiny stuff. 

Leave Lethal for the truly skilled people.
