Welcome to Mechspecs! Btw, I don't think you have enough firepower for a Heavy Mech. You may want to try reducing your DHS count to about 14, and adding a few more MPL.
Thank you for the welcome. I wanted too but my heat discipline is not great & I was not keen on dropping the engine size. I am leaning towards the WHM not being very XL friendly. At least for me. I am going to play around with it when I have it elited. Had some good matches though. I had one which I wish I had a screen shot of, 900+ DMG, 8 Kills, 4 Solo Kills & 5 Kills most damage dealt. Way better than my normal performance.
With XL and shave a wee little bit of armor you can go a wee little bit faster, and a wee little big more wubs, and a wee little ams, which makes ie wee little bit better. You can shave less armor for less ams ammo if you want, or do something else if you don't ams.
