Very fun poking / poptarting mech, with a very active playstyle. Vindicators are highly underrated these days. Relevant quirks: Energy heat -10% PPC heat -10% PPC velocity +20% Armor +11 to +14 to all 7 components. The superbly quirked HPPC when installed in the left arm sits on top of the arm, which is a bit higher - nice. ERMLs vs. other medium/small lasers give you a bit of range to play with and keep away from the 90m min range of the HPPC. Good amount of jets to get to high platforms, poptart, and/or spread incoming damage. Here I installed a BAP to improve sensor range and target information time - you don’t have a lot of dps so it is better to know where to aim that HPPC before you jump or peek. It can easily be replaced by more JJs, DHS (not really needed), or AMS. Note: I tested this build not fully skilled and with a lower rated engine (XL270) and dual AMS instead. Worked just fine that way too, but the added speed of XL295 should be good.
Why not fitting a TC1 and another JJ? I'm not sure about targeting info speed, but increased ERML range, HPPC projectile speed, overall increased crit chance and an additional JJ for even higher height and slightly faster fuel recharge compared to the same height seems a good trade compared to only a targeting info gathering and sensor range (ECM counter is very situtional with such a build)
