If you want to always have dibs on getting into Raid or Dungeons being a Tank is the way to go, and if you are Warrior Tank well that justs the cherry on top. Tanks are always in high demand and if you are unsure how to complete a Dungeon or Raid some players will be happy to teach you if you ask. When it comes to PVP Protection Warrior can be useful Flag Runners if they have a Healer pocket them, even without you can make due.
Your main damage cooldown is Death Wish, which boosts your damage by 20% and gives you fear immunity at the expense of taking 20% more damage for 30 seconds. It has a 3 minute cooldown, so you’ll want to use it at times that’ll allow you to use it as many times in a fight as possible. Unless you specifically need to save damage cooldowns for a burst phase, you can use it at the beginning of a fight and on cooldown to maximize uptime.
The leveling guides on my site are essentially speed leveling guides. My leveling guides are the same guides I use myself to speedrun to 60 on new servers to get 60 server first. I list many occasions where I tell the player to "die on purpose" to go faster. I tell the player to skip certain quests, because some quests are just not worth the time/XP. I list tricks and shortcuts to go faster so you can reach level 60 much quicker. I am still constantly going through them over and over again perfecting the guides to make them faster and easier to follow. For the most part, the guide can be followed without the need from other player's help, as the whole guide was made from a solo run anyways. Although I do list quests that can optionally be done if you have a group.
