Okay, so this has been on mind for a while now, Every time I play a game against healers, our ADC gets his 3rd item brawlers, then makes a build that absolutely makes no sense at all after that, and furthermore, he becomes practically useless against tanks, whether it
Brawler's Beat Stick or 
Toxic Blade. I don't watch that many SPLs ; however, I don't recall or remember an ADC building an Anti-Heal item at all, even if the enemy has multiple healers. My personal opinion is that an ADC should NOT build anti-heal, an ADC should be able to carry late game and able to kill no matter what the target opposing him/her , though they should go for their ADC build that will let them do so, furthermore late game even if the enemy has healing an ADC with right build will be able to kill that god no matter what, for teamfights, I personally think that mages, and guardians should apply anti heal whether it is by bursting the enemy with 
Divine Ruin or being in the middle of the fight 
Pestilence. Assuming I am a typical physical ADC, I would go like this 
Transcendence, 
Ninja Tabi, Executioner, 
Deathbringer, Qin Sais, 
Titan's Bane, If I remove Transcendence, I basically have no damage source and therefore weak AAs. No Boots = No Escape, Slow rotations, Whether you remove Executioner or Titan's Bane, you won't be able to penetrate through tank's defenses, you remove 
Qin's Sais, you have no way to chop through them if they have a lot of health build, you remove Deathbringer, you will have to land every single AA without missing and could probably be shut down before taking down the enemy, logically, if an ADC would not build a defensive item to make him/her survive in order to have the maximum damage output to the enemy, should they even consider buying an Anti-heal when they can have a confirmed killTherefore, I am asking whether or not an ADC should have anti-heal in their build, or even consider having anti-heal.
Sometimes you are playing with brianless people and they don't do anti-heal, so I don't think say "don't even consider do an anti-heal" is something good.
Also the actual meta needs two critics to work well on DPS, so I recommend you change the
Agreed on your points for reasons why standard, physical ADCs should NOT get anti-heal items. Specifically the points about them being able to take down healers quickly, and that it just fits other builds better.
A specific point that you didn't mention in the general sense, though you gave reasons in your item discussion, is that most anti-heal items usually will cut into the physical ADCs damage output overall.
Now, for your suggested items, I respectfully disagree with the overall standard build and item assessment. Here are my points:
In addition, for most gods not including the previously mentioned, it's pretty important to get 2 crit items, not just 1...25% crit chance isn't very high and thus not very reliable in increasing average DPS. You generally want at least 50% in this meta to get reliable DPS, which means 2 crits.
In addition, there is some inefficiency when getting both of these...the way protection reduction and penetration interact, the % prot reduction from Exe is calculated first, and TB's %pen will only be applied to the reduced protection, decreasing its overall effect. I discuss this in my items guide in the Protection Reduction / Penetration chapter.
One thing I didn't mention is that, in some unique cases, building anti-heal IS viable. That would be for hunters playing in the mid-lane, or maybe
So, here would be my three suggested "standard" build paths for hunters.
Basic-attack reliant crits:
Basic-attack reliant Qin's (Qin's wants high attack speed to get as much out of the passive as possible):
Trans build:
And not on the ADC. If you are against like Anubis, Hel, Sylvanus, Ao and Chiron I would maybe allow the ADC to go for a Toxic Blade (if he is going Qins build). But not really..
