MO1 had a lot of counter intuitive systems.
For example...
You try to go and attack a player, you instead have a pet put on you that you quite literally can not fight. The player you tried to attack has to do absolutely nothing but run / avoid you while his pet attacks you. Pets have no stamina, stupid amounts of HP, some have crazy AoE attacks, ranged attacks that ignore blocks / parries, etc.
You go to siege and enemy guild, but you instead are met with people spamming fire arrows, using elementalism, and spamming 'guards' so that their AI take care of everything. Sieges are stupidly unfun and one sided, and are usually met with very boring, uncounterable tactics. So what do people do instead? They ninja siege, they siege quite literally to avoid any kind of resistance from the other side. How the fuck is that good gameplay? "Lets stay up to 4 AM guys and siege X guild because they wont be online, we'll just be playing by ourselves and claim victory with no combat!!!"
You're new to the game and you want to be self sufficient, but the problem is you were limited to four character slots; and even when you wanted a character to 'do something' you were so specialized that you had to either gimp yourself to do what you like or bite the bullet and only do a little bit of each thing. You need armor. So you need an armor crafter. You're going to need a character who can do some form of damage, if a mage you can go into pets; if your a mounted or foot character; you're going to need weapons. So you'll now need a weapon crafter as well, but you wont even be able to make every weapon or use every material. Oh, you also need food. If you want to ride around, you need a mount. So you need a tamer to get around efficiently. Oh, you need the materials to make all this shit previously mentioned? You need an extractor / refiner. Like I understand MO1 was about making players work together, but I never understood the finite amount of points we were given as well as being unable to at least craft shit and use combat skills on the same character.
You want to go farm gold and make money, but in-order to do it efficiently you basically have to have a mounted character who rode circles around something and just pelted it with arrows or use a pet to do everything for you.
The game was just tedious all the way around. Hardcore, sure. Tedious, definitely fucking sure.
I'm not saying things should be super easy or grant you instant gratification, but... lets go back to these previous points.
Maybe don't allow players to have a pet play the game for them? Make it more active or involve some actual skill instead of "Pets attack all!"
Maybe don't design a siege system that is nothing but boring, monotonous gameplay with the outcome being avoiding any kind of conflict or dealing with a barrage of fire arrows, elementalism magic spam through walls, and guards just zapping your shit. Maybe make it more like Darkfall. With certain times, and notifications, or something that makes people actively engage one another instead one side just bunkering down and doing fuck all or one side just doing the siege when no one is online.
Maybe don't restrict our points so much, or give us crafting points as well so we can do more shit on the game and not be so strained to buy more accounts / character slots to do what we need.
Maybe don't make farming and PvE so boring and mind numbing that the people who are known to do it constantly are usually labeled lifeless and losers.
You had inbalances, bugs, exploits, terrible patch direction, no transparency at times, data breaches, etc.
MO2 has the potential to be good on a fresh slate, new optimized engine with tons of support, and taking in feedback. So HOPEFULLY SV will actually continue to listen and not try and veer in some 'over the top grand vision' of things being a specific way regardless of how people feel.
