You do know one of the best players during the MO2 Alpha was/is an American ?This is a strawman argument. Feedback has been provided, and the feedback was the desync was making it impractical for anyone outside of EU and perhaps east coast of NA to actually play and compete with EU counter parts. Feedback was also provided by many saying that they should consider having a NA server. What do you want me to tell you? Henrik is going to do what he's going to do. They only want the feedback they want, and some things he's not going to budge on. It was the same deal with MO1, the only difference being is they didn't know any better back then.
So how does that arguement hold any truth ? If 1 American can overcome ping why cant the rest ? Why do all Americans who cant get good blame things out of their control when we know of NAs who can beat EUs ?
I dont believe you played before and after ping normalization since you think desync was present. Ping was present making "desync" vs lower ping players as their attacks cut the animation short and hits went through blocks, this is still happening now vs UK players.
Now on to some desync issues that worsened over time from faster combat to alot slower combat.
Humanoid bug was introduced with the Bakti patch when combat was at its lowest so far in Alpha, warping/teleportation during group fights was introduced with Bakti patch(small movement sync issues was always present but warping/teleportation came Bakti patch), stuck on your screen humanoid bug came with Bakti patch.
Feedback is a weird thing when bias is allowed.
In the beginning of MO2 Alpha movement was faster than now and swing speed was faster than now. Both was increased in first patch due to massive feedback from testers.
Fast forward some weeks after more players join and the top players have learned the combat and is dominating being able to beat upto 10 guys in a row, No healing ingame meaning unless you died there was no way of gaining health. As said a few weeks gone with no complaints and suddenly complaints start about combat being too fast. This did not stop until combat got so slow and easy its now known as Parrywhore Online 2.
All the while nerf after nerf came to limit the skill ceiling the ones who complained was getting humiliated in combat, first with Meduli patch did the worse part of the testing community start to manage to block the right way since they now have enough time to react for their lack of training and experience.
Now the exact same thing happened in MO and you guessed right, its the same goddamn players influencing the imo negative changes. Coincidense ?
Then now my question is did they not learn anything from MO, do they think MO2 will have any other result than MO if you copy the development direction and doing the same mistakes once again ?
