TDR-9S Straightforward Firegroups: 1) Alpha LLas 2) Alpha MLas 3) LRM10 Engage the enemy from medium-to-long range, while providing an effective missile screen for your team. Apply double the pain to anyone who closes to MLas range. The high-mounted ERLLas and LRM10 allow you to shoot from behind cover with minimal exposure to direct fire, while the double-AMS provide some protection against counter-battery fire. This build is the slightly-slower long-range counterpart to AdultPuppetShow's "Berserker," for those that don't anticipate closing to MG & Flamer range. LT Satisfactory's MG Variant: TDR-9S ...lose a bit of top speed and pick up a pair of crit-seekers. If you want a 4th fire group, this is a fairly painless way to fit it in.
Agreed--I'm not a fan of running four weapon groups myself, but it's certainly a viable option for those with a better control scheme than I'm working with. Added it to the OP. Thanks for the feedback!
I just bind machine guns with lasers. Since you can let off the trigger after the beam starts you don't waste much ammo at all taking long shots.
I think your AMS and LRM ammo are short. I'd drop the engine to the stock 260, pick up an extra ton of AMS and LRM ammo and put a DHS in the arm. Like this: http://mwo.smurfy-net.de/mechlab#i=155&l=c5c90a9181013973c26419685a0563cbd3090dad
AMS? Perhaps... two systems do tend to chew through ammo. LRM ammo? No way... you only have ten tubes, so 2 tons of ammo gives you 36 volleys. That's the same number of shots I get out of missile boat configurations (I target 6 tons for 30 tubes/8 tons for 40) and it's only a secondary weapon system on this rig. How often are you taking 54 LRM shots in a match? Personal preference, I suppose... if you're already going to downgrade the engine to stuff in more AMS ammo, I guess you might as well run the stock engine and grab the superfluous ton of LRM ammo as well. I'd be more inclined to up the armor, or take a third ton of AMS ammo myself. Thanks for the feedback!
I was revisiting this build for someone on a fairly new account that snagged the recent free mech, and realized that you can achieve the same damage output without the Endo-Steel, at the cost of a bit of speed (260 stock in lieu of 275), a bit of armor and one AMS, if you're looking to go cheap and don't have a lot of parts laying around. Total cost to outfit from stock is just over 1M c-bills, if you're buying everything from scratch, but the result is a respectable grinder build: TDR-9S Alternatively, you can downgrade the LRM10 to a LRM5: practically max out the armor, keep the double AMS and pick up a bit of cooling: TDR-9S
