Recently, due to "Frostmorune seasonal" realm, new characters are by defualt on "Frostmourne season mode". They are at season 6 right now; so the best gear available is Ulduar/Furius gear.
In this "mode" you play against "Frostmourne" players as well as other "seasonal blackrock" players
I guess you have noticed that by talking to "Info and presets" Npc, you can enable "Season 8" mode. By doing that you will face "Icecrown", "Lordaeron" and "Season 8 Blackrock" players.
About talents, you can change the talent by talking to "Class Trainer" npc. It should not be hard to find him since Npcs are all in the same area (he is next to "profession" npc)
