Honestly, I'm less convinced of that and more convinced it's a function of raging about a restriction of druid character behavior in the rules. So I think it's more about contrariness rather than an analysis of whether it is a rule or not.
All druids in the world disappear. Bam! All druids in the world can wear metal armor. And heavy armor. And anything else you wsnt.
Where do the rules suggest I should lose my Druid powers?
Will not also (at least implies) is a choice and you can change your mind later
In the same way than the existence of the Flat Earth society shows that there is no consensus on the shape of the Earth. There is not any sensible argument for it not being a rule. It is printed among other rules in several places in the rule book, giving clear and explicit instruction. We might just as easily claim that dwarven armour training is just fluff and mountain dwarves do not actually gain mechanical armour proficiencies.
In witch case you are assuming I am raging (with no reason to suspect I am) and that I am being dishonest… I believe the rules here are very clear to interact with others you must assume them to be upfront
This seems pretty insulting
But that choice is in the past. No, according the rules druids cannot change their mind on this. This is why a lot of people don't like this rule; I get that, it is weird. But that still is the rule. Not a good rule, but still a rule.
Yeah, that makes no sense at all. According the rules a druid definitely can use such armour. Your GM effectively houseruled an additional restriction on the spot to screw you over. Which of course is technically within the rights of a GM to do, but it obviously is terrible game mastering.
