I only play Sona, so I cant speak for other Enchanters, but unless she builds Locket, Sona only has 84 Armor and 38 MR at level 18. If "everyone" is building Locket... well, that sounds to me like an issue with the item, and not Enchanters, no?
Even still, Locket doesnt give very much base stats on its own, it's usage is in the active. And I can tell you from experience, 114 armor is not going to stop a Zed or a Talon or whatever assassin from tearing through you. Hell, really the Frozen Heart of Spirit Visage I build is just to give myself just that extra second to react to an assassin or diver jumping on my face, because getting instantly obliterated isnt ever fun.
You say Enchanters build "minimal" AP... what exactly is minimal here? Do you expect them all to build AP items, as in the stuff mages build? Supports are supposed to be able to function on a lower budget, and full mage items can get prohibitively expensive on a support's income.
As Sona, my endgame build looks like

This build, along with Gathering Storm, gives me a nice hefty amount of AP to work with, and this is as Support Sona. I could take Redemption for more Heal and shield power AND AP, as well as the active... but I sacrifice it for my own survivability, with either
or
, or
if the enemy teamcomp is filled with crits everywhere. Does this make me tanky? Heck no. What it does is it gives me just that extra second or two of survivability to try and protect myself against an assassin or diver who has infinitely more mobility than me. It also helps when I inevitably take collateral damage because I need to be near my allies in a fight to support them, and that puts me in the way of attack.
If the enemy Zed gets fed off of mid and decides to turn his gaze botside, then if he even looks at me funny I just fall over. I should be allowed to sacrifice my power to try and give myself a little more protection against him. Otherwise how is that fair to me that I basically am not allowed to exist ingame because he's running around? He still has the heavy advantage, and can still kill me easily even through all that armor, but this gives me a second to react to him.
And that's not even getting into the MANY Sona players that only build her full AP, whether sololane or support. AP Sona's healing and shielding is more powerful than Support Sona's, but she pays way more for those mage items she's building
Sona is one of the few that actually builds more AP than most. Also spirit visage gives a lot of tankiness alone. building JUST it on an assassin can make you bruiseresque. If you really want to know just how bruiser-like enchanters are becoming, I'll repost something I posted on another thread a while back when we were talking about this issue, but before that, I must say, the thing is, you're not SACRIFICING anything but damage when you build items built for tanks or bruisers, and as an enchanter, all you need is your insane shields, which you get because heal and shield power are all you need for your scalings to barely make a bit of difference. You don't sacrifice any utility for tankiness as an enchanter, only damage, which you don't need anyways because your base damage is enough. Anyways below is a full detailed list of the enchanters and their most common builds:
Locket: 30 armor, 60 magic resist
Redemption: 200 HP, 50% health regen
Mikael's: 40 magic resist
Zeke's Convergence: 60 armor, 30 magic resist
Shurelya's Reverie: 200 health
That's 400 health, 130 MR, 90 armor, 50% HP regen(Most likely 100 MR, 30 armor, 200 HP, read below)
All of these items are Lulu's top item choices btw, obviously she'll swap out one of these items for her ward item, but she's still gonna have around 100 of each stat, because they mostly build tanky which means Shurelya's is likely out, and probably Zeke's too, for Ardent, but that means she'll have 100 MR, 30 Armor, and 200 HP. So maybe it's not 100 of both, unless she sacrifices ardent, but she definitely has more defensive stats than she should. Another thing to note at one point Knight's Vow was one of her top built items. Kinda crazy how an enchanter support can build whatever they want as long as they have 3 core items.
Redemption: 200 HP, 50% HP regen
Locket: 30 armor, 60 magic resist
Mikael's: 40 magic resist
Shurelya's Reverie: 200 HP
Warmogs: 800 health
That's 30 armor, 100 magic resist, 1200 HP, 50% HP regen. Again, one will be swapped out for Ardent and that's most likely to be Reverie, so 30 armor, 100 MR, 1000 HP.
Redemption: 200 HP, 50% HP regen
Locket: 30 armor, 60 magic resist
Mikael's: 40 magic resist
Reverie: 200 HP
Remnant of the Ascended: 200 HP, 125% HP regen
400 HP, 175% HP regen, 100 MR, 30 armor. This one builds Remnant of the Ascended, so even less AP than the others. You'd think Nami would be one to build more, wouldn't you? Guess not.
Redemption: 200 HP, 50% HP regen
Locket: 30 armor, 60 MR
Athene's: 30 MR
Reverie: 200 HP(She also occasionally builds Mikael's, by now you know it's stats though)
400 HP, 50% HP regen, 30 armor, 90 MR
Redemption: 200 HP, 50% HP regen
Locket: 30 armor, 60 MR
Athene's: 30 MR
200 HP, 50% HP regen, 30 armor, 90 MR(FOR SURE anyways, read below)
Sona apparently builds more AP occasionally, so I'll only list these three. However she also occasionally builds Remnant of the Ascended, Mikael's, etc like the other enchanter supports when she isn't busy building Lich Bane/Watchers, so she could have more defenses if she wanted it, more AP isn't NECESSARY, people probably just prefer trying to kill people when they play Sona.
Redemption: 200 HP, 50% HP regen
Locket: 30 armor, 60 MR
Mikael's: 40 MR
Shurelya's: 200 HP
400 HP, 50% HP regen, 30 armor, 100 MR. She also occasionally builds Ascended over Watchers, meaning another 200 health and 125% HP regen
And finally
Zeke's Convergence: 60 armor, 30 MR
Remnant of the Ascended: 200 HP, 125% HP regen
Redemption: 200 HP, 50% HP regen
Shurelya's: 200 HP
Knight's Vow: 250 HP, 40 armor
100 armor, 30 MR, 850 HP, 175% HP regen
This is all without counting boots, which could be either 25 MR, 20 armor, or 10% CDR/Mobis All boots options are highish up there so they could have more armor/MR if they want it.
They all have around 100 MR and 30 armor except Rakan, who instead goes for 100 armor and 30 MR instead, and they all have 400~ extra HP on top of that.
Remnant of the Aspect:350 health, 200 HP regen
Locket: 30 armor, 60 magic resist
Redemption: 200 health, 50% HP regen
Knight's Vow: 250 health, 40 armor
Zeke's Convergence: 60 armor, 30 magic resist(or Righteous Glory maybe: 400 health, 30 armor, 100% HP regen)
800 HP(Or 1200 with Zeke's), 250% health regen(350% with Zeke's), 130 armor(100 with Zeke's), 90 magic resist(60 with Zeke's), just for comparison. The only real difference is Ali builds more health and more armor than most enchanters, but really he's similar to Rakan's stats outside of the MR, and Rakan originally was supposed to be built more squishy. So why does Rakan have similar bonus stats to Alistar?
Btw this is all bonus stats, base stats aren't added in. Most enchanters seem to build heavy magic resist and at least 400 extra HP. Probably why I hate enchanter supports so much, considering I mostly play Katarina. Their peel is too strong, their resistances are generally too strong, and they give ADCs shields the size of half their HP or more, making it hard to kill either one. Redempion doesn't even RESEMBLE an enchanter item outside of it's active and the shield/heal power. This is why I'd much rather Shield/heal power be removed and nothing else change for shields. The moment that stat came to League of Legends is the moment enchanter supports became overbearing. Remove it and supports will build based on actives and passives instead of what has the most heal/shield power and then straight tank.
