1.8.1's latest.
I never really had an issue in the factory (apparently some complained "no one bothereed even going through the factory to test the balance"... but I did countless times, and never knew it was an issue till that thread).
Of course TSLRP's factory (which was a 20-fold harder) learned me the hard way how to build HK, that might have helped, with ample repair, dual-wielding instead of one assassin rifle, using mandalorian rippers, keened out with heavy +crit modifying and general damage adding modifications.
Becomes pretty easy like that. So yeah, never really noticed some players might think it would be slow and tedious.
Anyway, was planning a small modification for said players who didn't want to improve their HK to lower the HP somewhat... however I... well... completely forgot. Let's hope I don't do so again when done with my work on M4-78EP. It's not really difficult to do. Just a little tedious and boring.
