Beginner in need for help.

I just started playing on WOTLK after i only played newer expansions like legion and bfa( not much) . I am a warrior and this talent menu is kinda new to me. I wanna know what is the best war class . Just for overall good use . For pve, dungeons and for pvp .

For PVE - Fury warrior talents (including raids and dungeons). For PvP - Arms warrior.
You should check the talent builds in warrior class section of the warmane forums.
