Where to go 49-50 solo

[Phinger]

So I just hit 49 and want to get to 51 asap. I'm an enchanter and usually charm solo. Where are some good places where i can hunker down and pump out the exp? Best place I know of personally is CoM but i've spent most of the 40's there and would like to go somewhere else.

Open areas with space to move, melee mobs would be great.
