I think it's more improper building of HK than them having many HP's. I notice everyone using the Droid Assassin Rifle. Weak. Power shot. Weak.
Dual-wield Mandalorian Rippers with Keen buff and even more crit hit damage (ontop of HK's unique feat to add crit damage)? Die HK-50 Die. They do die in 2 or 3 shots as that. And I know, since I did it.
And thus never realised how apparently they would have too much HP otherwise.
Also, as mentioned, 20 times less than TSLRP which I first got through the droid factory with.
Apparently people here disagree with that too?
Because everyone knows how to build the exile and the lightsaber. HK and blasters? Not so much apparently. I think nerfing the game would weaken it, instead of making people realise how to more efficiently play.
Learning through conflict and all, Kreia/Echani style .
I did. Except for the very last run I always went through it "clean", as a regular player would with regular gear. With enough repair skill, HK can even make some kickass blaster upgrades if you haven't pre-made it as Exile/Bao-Dur before.
And as stated, I never felt it was too hard, or took too long. Not even with the HK-51's. Until you had to kill them 5 times over to test bugs/fixes... but that wouldn't be the case for the player.
