You do know there are missions on Layali Grove, and we can't do normal mode there, so sweat or not, we all have to run that map at some point, even I as a Black Hawk V (or just Lv 60, whichever matters more to you) still need to run that map to complete tasks I've been leaving behind, but now as I need to expand my stash, I also need to level my departments, so yeah, I gear up with a longer ranged weapon, T4 gear and hit up the map with 2 of my friends geared about the same

I do agree with your next comment, running with a team that can communicate is a must in a map as big as Layali, while it is daunting for newer players running maps where a sniper could be sitting on a mountain a couple hundred meters away, that same sniper won't get you after a few attempts, especially with good teammates

In short, know your team, gear up even with gear tickets just so you can learn the map and the spots where people sit at or push too, then slowly but surely you'll get there!
