I've Master on 3 of the atlases and probably enough XP above that to master the 4th if I wanted it (which I don't)
I disagree that it's about charging in first and being the "tank" - because of your (lack of) speed and rather large hit box if you are the first one into the fight more often than not you're going to get focus fire and die rather quickly or at least end up badly crippled and then limp around for much of the match waiting to get picked off.
Atlas is actually more dependent on the group being smart than quite a few other mechs. What happens when the group is moving as a unit and they spot a lone jenner on the radar? Yes you guessed it, more often than not many people will peel off to chase the squirrel.
This leaves your lumbering brick of a mech alone and rather vulnerable if it should be unfortunate to encounter an enemy group (even a small number of lights can be problematic)
It's actually better for harrassers and lighter/faster mechs to go in first or go over the crest of a hill, they have more chance of evading fire and getting in/out.
I found while pilotting the Atlas, especially the DDC, I have to keep an eye on the minimap and try to best situate myself depending where the group is. You have to judge when it's best to make a push forward and when to unleash the burst damage, and hope the rest of the team piles in as well. If you just wade in right at the start most of the times I've found it's a losing proposition.
The best time to "tank" is when the engagement is already on and enemy mechs are distracted or not focus firing, you can then wade in and soak up some damage and help out your own guys who are in combat, killing things in short order or surviving enough vs 2-3 or maybe more enemies if possible so that your guys can get the drop on them.
Using buildings for cover, moving around "hiding" etc. is playing smart, waiting for the right moment to step in and either kill things or soak it up when needed. It can make a difference if you manage to surprise an enemy as they turn a corner and go face to face with an atlas - I've lost count the number of players who've gone into a panic and overheated etc.
Charging in from the start/lead is asking to be focus fired to death.
As for longer range stuff, well the maps are getting bigger. Short range brawler can only go so far, especially as they add in more bigger maps.
