Overall the Wildkatze is a pass for me. Weirdo already pointed out the armor issue and added to that there's the following negatives for me:
- Sub-standard fuel.
- The light engine only saves you about 1M CBills compared to a XLFE, but you lose 3.5t extra payload. Personally, I prefer a high/low (XLFE/SFE) mix of designs, with the LFE being neither fish nor fowl.
- The binary laser doesn't really gain you much for the added investment compared to a LL, LPL, PPC, etc. LLs, etc are already capable of thresholding the vast majority of armor arcs on canon ASFs, and the few arcs they can't, but blazers can, belong to heavy fighters that will trash a Wildkatze. Sure, they do extra damage, but is the 2 extra points compared to a standard PPC, for example, really worth the 6 extra heat and 2 extra tons? As one alternative, a PPC and an ERML do more total damage at the same range for less heat and tonnage.
