Actually, your first response was to
"There are plenty of interactions you can exploit. For example, cast Suggestion on a Dragon, cast Nystul's Magic Aura on the Dragon, and then cast Planar Binding on the Dragon. Or use Magic Jar to become a Duergar Despot to avoid Exhaustion when using Convergent Future. The oldfashioned Wish-Simulacrum-loop resulting in resistances against all damage types for the entire party. Infinite Magen as a Necromancer Wizard as long as you find enough quicksilver. The list goes on. If you want to break the game and if you're into powergaming, there's always a way. And as long as it's discussed with the DM beforehand - as everything should - it's all cool."
And your response started with
"This stuff makes me laugh so hard. All the exploits that rely on overcoming a clear and obviously necessary restriction."
My point that DMs need to do their homework came much, much later.
The only one that is aligned with the wording of the rules and that doesn't involve bending over backwards.
The only one who spoke in absolutes in that regard was you. I emphasized the importance of session 0 and setting the rules for the campaign, whatever they may be.
Man, you flip-flop harder than a politician who was caught red-handed.
