The downgrade from LRM20 to LRM10 made sense because the launcher is limited to only 10 tubes anyways so it allows for much better ammunition control at the sacrifice of fire rate. The ER Large Lasers and AC/10 can pick off enemies at long range while the medium lasers and SRM6s come into play once a enemy gets into medium to short range.
A few thoughts on the setup (asked by myself while working on the setup):
- Q: Doesn't this undermine what a Atlas is commonly used for?
- A: Yes and no. The Atlas is intended for heavy frontline combat. Being able to reach enemies at greater distance doesn't change that. In fact, a skilled pilot could actually put more pressure on enemies, allowing for greater coverage and ultimately drawing more fire onto itself.
- Q: If it comes to brawling, isn't this configuration too weak to keep up?
- A: The Atlas's greates wekness is it's own weight which results in very low cruising speed so people often prefer hard hitting weapons for short range encounters to prevent a more agile enemy from circling around, hoping to kill it in one clean alpha strike. The AC/20 does that best but the AC/10 with its higher rate of fire is more forgiving on a miss, trading the one-hit-kill for more reliability and range. But in the end, I've chosen it to open up some tonnage for the ER Large Lasers (which can also hit at short range but because of their heat generation, I would not reccomend to do so).
- Q: Speaking of which, what do you hope to achieve with the large Lasers and why the ER variant?
- A: The ER coice is up to discussion but ultimately, I chose it because it weights the same and has only slightly increased heat buildup compared to the Large Laser but can reach almost 50% further. Large Lasers are also great weapons that can reach enemies at a long distance. It puts pressure onto enemies that have to coose between retreating and retaliating, especially if they don't have some of their own. It'll either draw them into the fight where the mediums can put more fire into them or reatreat where they can't shoot back (maybe even causing them to back into their comrades which would be even more fun, especially if they are still in your line of fire).
