Recommended role: Brawler, first line assault. Recommended mech modules: Radar Dep, Adv Seismic Recommended weapon modules: AC20 range 5, AC20 cooldown 5 Recommended playstyle: Keep with your team, help them gain ground. While moving up, hit the enemy with the LRM's and LLAS, when you reach sub 300m hit them with the AC and MLAS aswell and abandon the LRM's. The LRM's in general is your third weapon and a strategic one more then damage dealing, stress the enemy, reach out and damage them on approach or when they run from you. You are slow so having LRM's as a third weapon sys is not too bad even with the ghost heat increase on LRM5's. Been doing well with it, getting 500+ damage games. Did this which was the 9th game with it.
What's better? 4x LRM 5's, 2x LRM 10's or 1x LRM20? AMS kills 4 rockets per volley right? but how does the heat affect each set?
On any mech, you have to look at the number of available missile ports. On IS mechs this is especially important since you can fire a larger volley rather then a stream of clan LRM's. On the AS7-S, you have 10/6/6/6. This means if you fit 4xLRM10's on it, you will fire a salvo of 10/6/6/6 and seconds later 0/4/4/4. This is highly ineffective as you already know with the AMS being able to pick off more missiles then ever with the new modules. Previous to the modules "AMS range 5" and "AMS overload", a single AMS could take out between 6-7 missiles in a stream. We have no facts on how many it takes out now. My guesstimate is around 10 missiles with both modules. In any case, mounting larger LRM's on the AS7-S is a waste of tonnage, IMHO but having 4xLRM5's is not. Now, ghost heat? http://mwo.smurfy-net.de/equipment#weapon_heatscale 3 is allowed, 4 LRM5's gives you a 1,68 heat pts extra per launcher. Normally a LRM5 gives you 2 heat per launcher but triggering four launchers gives you 3,68x4 = 14,72 instead of 8. This is manageable since you will not be using the weapon in close ranges, I plan to run low on ammo or use it only when the enemy is faster then me, retreating or while I am approaching them. LRM's are excellent for making people duck. Sorry for the rant, I wanted to give you as good an answer as I could, it became a bit long...
