True concealment is fine if you reduce the timer to compensate but otherwise makes tactical missions much easier. I would still like to have some missions in LW2 play by those rules but not all : more mission diversity would make the game (even) more enjoyable and it would help make multiple squads viable. The WotC order just makes the entire game easier if you draw it and since it's totally random i think it's a bad idea.
The concealment mod i use is Peak from Concealment. It's just a very simple change but one that makes a huge difference for me as stealth becomes much more natural. You definitely don't play a stealth mission the same way when you can take a look around a corner to see if the way is clear or skulk on a roof without the goons in the street spotting you. I think part of what makes stealth unfun for many players is that it's so far away from the images we've all seen in movies. Nobody tries to stealthy infiltrate an hostile area by walking in the middle of the street but that's what XCOM2 gives us for stealth since approaching LoS blocking from full cover is the best way to get spotted without PfC
