Anyone who has ever played an MMORPG knows that the best experience is when you play with friends, and yet, for whatever reason, MMO-makers seem to put dozens of hurdles to prevent this from actually happening. With Guild Wars 2, ArenaNet has implemented a number of systems that have the capability of completely changing this. If you’re a max-level character, you’re able to quest with your low-level friends without any penalties for them or punishments for you. In fact, it’s encouraged.
Traveling to a low-level area decreases your stats to be in-line with the area’s. You still have all of you items, spells, and abilities, but it’ll still be a challenge to take things down – as it should be. This means when your friend starts playing you can jump in with them at literally any level.
This has interesting cascading effects that sound absolutely stunning. If you and your friend make characters of different races, for instance, you can just travel to one area and complete all of the missions before going to the other one, and doing all of those. Since it scales you to the optimal level it just means that there’s more content for everyone. You can even transfer between servers temporarily for free to play with friends (though your home server is still an important distinction for PvP and other elements).
