Raid Boosting Services
Destiny 2 Raids are unique from other MMOs, in the sense that no matter how long ago the raid came out, there's still reasons to go back and attempt to complete them. The raids can drop extremely powerful Exotic Weapons, and the gear obtained from them is still useful in reaching certain gearing requirements for other types of content. Each raid has both a Normal and a Master mode, to provide players who are up to it with more of a challenge.
There are certain very powerful weapons in Destiny, known as Adept, Timelost, or Exotic weapons. These weapons are extremely powerful in almost all forms of content. Due to their power, they're usually extremely difficult to get, and require many weeks of completing raids, or very specific requirements throughout a raid to obtain them.
Completing a Nightfall Strike may not seem that difficult, but finishing with a score of over 100,000 will earn you high end rewards that can help get your Guardian as strong as possible.
PvP Boosting Services
There are many different types of PvP in Destiny 2, but there some of the rewards from PvP have proven to be very useful.

Most types of PvP in this game have a level playing field, where gear doesn't affect how much damage you deal or receive, but events like the Iron Banner allow you to use all of your hard earned gear to it's fullest.
Seals are a way for Guardians to express some of their most prestigious achievements. Completing a Seal will grant players with a title to show off that they've mastered certain aspects of the game.
