Before I'll offer an oppinion on this topic I'll just say that I've been an Atlas pilot for years (since MW2) and have not piloted anything else since joining the ranks of Mechwarriors in MWO. So, I feel able to offer a valid perspective as solely an Atlas driver.
An Atlas with a skilled pilot at the controls is fearsome. It is however very unforgiving and, for inexperienced players, is difficult to deploy correctly. The principal difficulty piloting the ATL7 is it's lack of speed. Assuming a 300 engine (normal or XL) the mech is sufficiently slow to make disengaging from the enemy nearly impossible. The job of the skilled Atlas pilot is to very carefully judge when to bring the mech's considerable firepower and longevity to the fight in order to make a decisive difference. Making this decission correctly comes only from experience.
Charging ahead in an Atlas - any variant or "build" - is suicide. There are very, very few situations in which this is a sensible tactic as an Atlas pilot and those few that do exist demand that the Atlas pilot must have a significant level of support - something that seems to be largely absent in most PUGs. I have a feeling that many new players see the walking wall of armour and believe that it will protect them from anything. Obviously this is not true. The Atlas demands a very refined skill set in order to be employed successfully and absolutely mandates an understanding of tactics and the ability to maintain situational awareness.
As far as the Atlases themselves go, obviously the ATL7-D-DC with it's dual ballistic slots and ECM is currently predominant. Some of this is due to the currently OP ECM effects but the DDC is inherently a good design as it has many hard points, and a good mixture of them, to choose from.
I disagree with the accepted wisdome that the ATL7-K is useless. There are a number of long range direct-fire builds that work extremely well provided that the pilot does not under any circumstances engage in brawling. Obviously with the small maps and extreme focus on DPS rather than longevity this does limit the effectiveness of the K variant in a typical 5 minute match, but it can be effective.
The ATL7-D is, in my oppinion, one of the weaker variants. I piloted the ATL7-D(f) for a
long time and had a pretty stable build of 2xER-LL, 1 x LL, 1 x GR, AMS, a pile of ammunition and around 29 SHS. Unfortunately the nerfing of the gauss rifle made this build barely viable as the design more or less required an XL engine. Replacing the GR with an AC didn't really improve matters. True, the ATL7-D is one of two Atlas variants that can carry two ballistic weapons, but doing so makes too many compromises in other areas to be as viable as the -D-DC variant.
The ATL7-RS is an interesting beast. I suspect that if and when the larger energy weapons get some sort of stat buff then I foresee the -RS becoming a very viable and popular variant. This variant has a good mixture of energy, missile and ballistic slots and a wide variety of very viable builds are possible.
If I were to make changes to the Atlases in general, they would be:
1. Make the ATL7-K or -D the ECM carrying variant. The -DDC is sufficiently powerful without this additional buff.
2. Give the ATL7-K an extra missile slot or extra energy hard points. Obviously it's designed for longer range engagements, something for which it's not best suited with current weapons stats and components behaving as they are.
3. All variants must come with a training manual on how to best employ the mech
