3.5 was edition I played the most. It was a reason why I quit RPGs for nearly a decade because I hated it so much.
Every time I see another meme about how amazing 3.5 Tarrasque is, I remmember how amogn actual 3.5 players Tarrasque was the biggest joke. It was always brought up as definite proof designers have no idea how to make good monster. It was laughably easy to beat. A wizard could casually solo it, the same abilities people now miss in 3.5 amounted to ribbons. It was a laughingstock, forums had 100+ pages discussions how to fix it and general consensus was it';s beyond saving. It was first proof in 3.5 if you cannot use magic you're only good to roll over and die.
I honestly don't know if everyone claiming 3.5 Tarrasque is such a horrifying monster are trying to rewrite history or unintentionally proving what a broken, unplayable pile of garbage 3.5 was, if it's biggest punching bag is actually dangerous in a different, better designed game.
Could you give examples? I never heard of it being easy to beat, and I would love a laugh at it being easily handled
The big one was its complete lack of mobility abilities or ranged attacks, so a party with overland flight could attack it pretty much with impunity. Iirc that was most commonly paired with shrinking a bunch of boulders, carrying them up with you, then dropping them right as the shrinking spell expired. This is all from memory 15 years ago though so details could be a bit sketchy.
