Just because it can...DOES mean it should!! 6 Large Lasers and nothing else. I know an XL engine may be a big no-no in an Assault mech, but the extra speed and weight for Heat Sinks makes up for it. I take Seismic Sensor and Cool Run (plus I have the Cool Boost unlocked). Can't do 2 Alpha's in a row, but with smart heat management and good aiming I dish out the damage. 3 LL to weapon group 1 and the other 3 to group 2. Give it a try, its super fun and scares the bejesus out of the enemy!
Given the ghost heat penalty for firing in groups of three, how is that going for ya? I realize it's doable to run a pure LL, or pure PPC build on alot of these Mechs in spite of the ghost heat but find that even one opportune alpha is rarely worth it. Are you making much headway with that build?
It's fun. On the non-hot maps 3LL generates 30% heat. 1-3 kills per match, but tons of assists and high scores with lots of damage (400+). This is also due to good aim and keeping the laser on target throughout its burn. Picking targets carefully and focussing on sections with no armor. This helps grind XP. I might drop to 4 LL and MG's with more DHS as well. I'm not looking at this as a super killer build, but a doable fun build.
