Honor and Conquest are no longer currencies. Honor Points instead increase your Honor Level. As you increase your Honor, you'll get gold, artifact power, and Honor Talents.
Honor Talents are an additional set of talents that are active when players are in PvP instances/combat.
In PvP content, you will get a preset set of stats for your specialization. Your set bonuses, enchants, legendary bonuses, or trinkets will be deactivated.
Gear can still improve your character in PvP, but as an example, a 25 item level difference will result in a 2.5% difference, not a 25% difference.
There are no specific PvP stats or fluctuating item levels in Legion. You can still earn some gear through PvP.
End-of-season PvP rewards will be awarded separately to the top percentages of players in each faction, not overall playerbase.
Prestige Levels: Reach Honor Level 50, which grants access to high-level PvP talents. Or you can turn in your Honor Level to gain a prestige level for rewards (titles, artifact appearance, mount, pet)
There will only be 4 prestige levels at launch, with more added each season.
Shorter PvP seasons mean more frequent rewards.

The base item level at 110 is currently set to 800. If your gear level is 810, your stats will be increased by 1%. So while better gear does offer an advantage, it can be more easily overcome than in the past.
