Progression is something I would call in a game, where you should clear VoG to have TDB opened up. Slaughter Crota to have keys to the Prison of elders and Petra missions. Then kill Skolas to open up the dreadnought and TTK missions. Progression would be feeling that your character is actually becoming more powerful. Not just by being able to tackle higher level monsters but to make lower level monsters seem weak and insignifigant. Progression is something between a Newbie and a seasoned player. a 6 month timegate. Progression is respecting the old players and giving a challenge to the new ones. And as far as the year 1 weapons go.. I really was going to leave them behind. But Year 2 didnt offer me anything to replace them. I had a blast shooting away with my year 1 setup.. I just dont have fun with the new weapons.
