Hello.
While a friend and I were considering how best to powerlevel each other's level 57 toons, we found something funny about Hellfire Peninsula instances.
The lvl 90 character, who was party leader, forgot to take off Heroic mode. We zoned into the instance (Ramparts) and it was Heroic Mode.
My friend was able to do full Heroic clears of most BC instances that allowed me to zone in for Normal mode.
I looked via Google to see if this was a recent thing, or if people have always been able to zone in there.
Most Heroic instances and high level content requires a minimum even level of like 70, 80, 90.
But BC stuff is either nerfed or broken and you can get your easy Double Achieves, 3 socket Epic gear for lvl 70 (including weapons), and instance completion credit.
The only downside is Heroics are daily reset unless u know a way to reset trash.
Ramparts is a really fast and easy reset on Normal mode, so after doing your Heroic you can just do a couple normals and jump down to the door. I think some people just park their toons by the front door and they get last boss credit if they are close to his room.

So as you can imagine we leveled thru BC real fast and needed to do some Wrath content.
We powerleveled using Azjol Nerub because of the portal at the end, i.e. easy reset and exit.
When we hit 72 we headed to Dalaran Violet Hold because you can just park the toon inside the portal, but behind the door, and the 90 or whoever can just clear the instance without having to protect the alt.lol
The Heroic mode exploit does not seem to work in WOTLK. It was great fun while it lasted and if this is a repost, my bad.
have fun!
