We don't talk about Pun-Pun
Look, I'm the first one to say I wish 5e handled magic items better than "here's some items, you can use them, I guess, we won't tell you how, so any mistake is on you". But at the same time, if a DM says "sure Mr. Eldritch Knight with PAM, have +2 armor, +2 shield, a cloak of displacement and a Staff of Power", and that causes issues, I mean, surely they could have seen the AC rising with each new piece of gear and noticed that, hey, my CR 15 dragon only has +11 to hit!
OTOH, without magic boosts to AC, some classes quickly realize they have no business whatsoever in melee combat, as AC quickly levels off. By level 5, a Fighter who wants it is rocking full plate for his AC 18. A few levels down the road, he might be looking at a CR 9 Fire Giant who hits that on a 7. Sure, he can tank his damage by switching to a shield, but that poor melee Rogue with his AC 17? Not good! So if he can stack a ring of protection with some other defensive item, it's not a problem unless his AC rises to a number the DM can't handle.
Also. If I reply to a comment that says: "Rings of Protection have never stacked with magical armour bonuses so why would I ever think they were intended to start now in 5e", saying "well, ring of protection didn't stack with shield of faith lesser deflect or a cloak of protection" doesn't make what I said untrue.
