Nothing in my post was hostile, so I would expect civility in return. I merely asked what the motivation for that setup was, and then suggested potential options providing different benefits depending on need.
From what I can make out, you don’t seem to care about his enchanting or his damage, and he doesn’t have any auras to buff you, so you just want him to survive and nothing else?
The plus to skills, which I wasn’t overly focused on, was about increasing the attack rating on his enchant. The damage on the enchant is not really important, which is why I was suggesting more skills instead of facets, so that you could get more attack rating. From your first post, I thought your reason for using the Act3 merc was for the enchant.
Again, like you, I don’t consider his damage worth much. As such, for swords I was looking for something to improve your damage (might aura), or provide safety (cleansing aura). The cleansing aura would also protect him from curses and poison. A faceted sword does nothing for you; it only adds to his very limited damage.
The Phoenix shield was more about survival than fire damage. His damage is a side benefit, but the redemption aura restores his life. Act3 mercs don’t have life steal, so this is a way restore his life. It does rely on you killing things, so if you’re not well geared, then I see why you would want more DR. If we’re talking about builds worth several high runes, I would have thought your damage was high enough to use this setup. You could combine it with Shaftstop to keep the DR if required.
Flickering flame was about providing fire resistance to both of you. Again looking for something to benefit the player. It also has the side benefits of skills for attack rating, and negative enemy fire resistances - which you seemed to want from your facet sword.
These were my ideas to provide more utility from the Act3 merc. If you just want a merc to survive, I had a budget Act5 merc with lawbringer and Sezabi’s set that only ever died to ubers.
