I can't believe that this wasn't deliberate.
Did he say "you die to trolls because you lack the ability to use fire"?
No - he said "having a high enough ac to matter against a troll takes cash"
And he's right.
In a low-wealth campaign, the winners are the magic using classes. Wizards, bards, clerics etc. Because a spell slot 'costs' less than the benefit it can give you when funds are low.
If funds are at the right level, it's a tradeoff whether it's worth taking levels of wizard to get mage armour, or taking levels of fighter and just wearing the magic stuff.
That's the big thing a GM has to keep in mind - not whether the party can defeat foes, but whether each party member can contribute equally.
If a troll would have an easy time hitting you, don't put yourself in a position where he can hit you. It's not the tools you have to use, it's how you use the tools you have. There will be times when you won't have the tools you think you should have. Not a dang thing you can do about it either. All you can do is improvise and hope things fall your way. Can't face the troll toe to toe? Then don't. Use rope, use nets. Get it bogged down in marshy ground or trapped in a gully. Get it confined and unable to use its strength against you. When you are at a disadvantage find some way, any way, to put your opponent at an even worse disadvantage.
BTW, who says every member of the typical party has to contribute equally in every situation? So the party druid does the bulk of the work with an
Entangle. Big whoop. You've got an immobilized troll and you can now work on oxidizing the bastard with extreme prejudice. There will be other opportunities for other members of the party to stand out. The goal of any adventuring party is not to shine as individuals, but to work together to accomplish goals. If it means the paladin has the limelight one day, then the paladin has the limelight that day.
No matter how you tweak things there will always be those who stand out, and those who stay in the background. It's how people are. You want folks to put themselves on display even when they don't want to. All in the name of "Party Balance". And so you would drive some out of the hobby who would've been quite happy acting to support the leads, and getting a bit of attention every now and then.
Let people contribute to the degree they feel comfortable. Never force people to do more than they are ready to do, unless it is a situation where somebody has to do something. And never manipulate a situation to get what you want. If it's to happen, let it happen naturally.
Believe me, shy people really hate being forced onto center stage when there is no good reason for it, and their revenge can be vicious.
In short, let people participant to the degree they want to. It'll make for better sessions.
As for trolls, they do have to breathe.
