Lets not spread misinformation. No encounters were worth more than others just arbitrarily. I went over this in a previous post. If you dont understand how the progression scoring works, just ask please. I will be more than happy to explain it one on one. Some plants were worth LESS because more guilds killed those first. There was 4 to choose from and some of the plants were just chosen more than others by luck of the draw. Same with the fairies. The guilds that got more points on one plant would have gotten less on the others so they would have balanced eachother out eventually. Every mob starts with the same point value every time based on its raid tier. It never changes.
Again, just so people dont get misled there was no ping ponging of any kind. Its pretty simple. Zone opened up. Zone has particular progression mechanic where you can only choose 2 of 6 mobs to kill per zone in. Guilds use Reset items (that some other guilds didnt have) and also used alts to open additional instances to get more pulls on encounters than would normally be allowed. (Gninja brought this very subject up and warned guilds of it) So, naturally people complained about it being unfair that some guilds new this ahead of time because of beta testing or exploiting or whatever and started a large discussion on discord. Hardly anyone argued against them at the time. Had there been more push back to NOT change things, they might not have been changed. But there were many more voices to condense the encounters as thats what was done. One modification. Not many times throughout the expansion. So please dont mislead people.
