Been a fan of the AC2 + LBX10 combo since I tried the 2x LBX, 2x AC2 build in my CTF-4X. Pierce through the armor with AC2 + LLas, then crit with LBX. Weapon groups: 1. 2x LLas 2. 2x AC2 + LBX 3. 2x AC2 (for pure long-range sniping) If heat is too high and you have to fire anyway, remember that a single shot of 2x AC2 + LBX builds up 4 heat units, the same as a single medium laser, yet potentially delivers 14 damage. If you time your shots, it's not hard to manage your heat.
