So I just bought the guide, but quick question! [Heirloom Related]

[uleet]

I just got back into World of Warcraft, and I just loved the aspect of being able to level up quickly so I figured I'd buy the guide. Awesome, but I'm a bit stumped.

Should I go out and take my time to do some PvP for heirlooms? Or is that not necessarily needed, I have heirlooms for a couple of Characters, Shaman, Warrior etc. But, I want to level up a rogue. Is it really worth the time to get the heirlooms for that xp bonus, or is it not that much of a boost in time due to the guide?

As you still need 2-4 days from 1 to 85 having the 20% heirloom bonus from 1-80 saves you a lot of time.
If you can get them in less than 10 hours played time I suggest you go and get them.
Remember that you can get the PVE heirlooms for Justice Points. Chest and shoulder cost 2175 JP each. However I don't have a clue how long it takes to get the 4350 JP.
You can also get them through the Argent Tournament. But as the quests there are dailies it takes a few days to get them.
