If you have to take shots from a lot of uncontrolled enemies AFTER your turn, YOU JUST DO THE TACTICAL LAYER VERY WRONG. You have to KILL, WOUND, SUPPRESS, DISORIENT and OUTFLANK your foes BEFORE they can shoot back! This is the number one rule of firefights, cover is just simply not enough.

XCOM is about controlling the tactical field just a real mission in real life military organizations. Some people just do not do the math - and whining about chances when taking fire from uncontrolled enemies! Without elevation and range bonuses, marking or negative Defense, an ADVENT Trooper will hit him in High Cover with 20% chance, an Officer will hit him with 30% chance which both are pretty high. As in my example above, the 'Average Joe' XCOM soldier has absolutely no chance against ADVENT is they have clear shots against him in High Cover. In LW2 this is a different story: the ADVENT soldiers are using a magnetic weapon which means they can simply destroy most cover elements with a few missed shots, so they are shooting constantly. Long War players are used to the feeling that High Cover is a great protection and most aliens in LW1 used overwatch or suppression against targets in High Cover, they did not shoot with low chances. IF YOU WANT CORRECT HIT CHANCES, YOU HAVE TO SET THE GRAZE BAND TO ZERO! The standard grazing chance (the Graze Band) is stupid and makes the game's tactical layer more unpredictable. The grazing mechanics are good if you set Graze Band to 0 because grazing means that a quick and agile character can dodge a hit for less damage, a bulky creature or soldier can be critically injured from a normal shot. Negative Dodge and Defense stats make it even worse. People I know are using the Graze Band (at the normal 10%) which means the enemy has 10% more chance to hit their soldiers. More fights mean more hits on both sides, and this is a new experience for most players. You can't sneak half of your objectives like before. You have to fight more missions in 1.3 (and later updates). In my opinion, players suffer from more hits because I played the game a lot and I played differently from the 1.2 version and YES, there are more hits against me but it is a fair business, not cheating. I added a simple example above in my last comment about the 'Average Joe' in High Cover.

I do not think that there is a cheat for the aliens after 1.3 update.
