Name 1 thing that goes to poop if Classic goes back to season 2 rules, you can't. There are plenty of counters to Golems as long as Mammoth buff is removed (Weight grapple, picking, stacking bleed from multiple bleed dinos etc, cannon(does like 3k pr shot), etc), and you actually need to be good to win open world fights without Gigas. The last few seasons of Classic has only had 1 thing matter for pushing: Giga melee. It sucks all of the skill out of the meta. With Mammoth buff enabled you can't even use fliers or anything to help win the Giga fight because you can't pick them, so whoever rolls the luckiest wild Giga melee wins the season.
You're saying it ruins the gameplay because it takes tons of time to take out enemy dinos, but the only dinos that even take time to kill in the classic meta are Gigas, Golems and Reapers(Maybe Stegos but they have nerfed resistance). If Reapers and Gigas are removed the damage scaling fixes itself, Spinos and other land dinos will kill each other at a similar pace to how Gigas do since they have much less hp. The only dino that doesn't instantly die is Golems, but not being able to counter them is a skill issue not a balancing issue.
Removing the big munch munch dinosaurs that have no counters is what everyone (except you) wants.
They tried seasons with them, now people are giving their feedback.
(Classic season 2 also had servers with reaching 100 pop less than a month before it wiped. The ruleset worked and everyone loved it. Season 3 and onwards has had much lower pop even though the game has had similar player counts up until last year where Gen 2 killed it.)
Ok I ended up writing an essay lol, if you have any arguments against my argument here I'll gladly explain to you why you're wrong.
