Secondly to that, I strongly encourage you to try the charm killing. My only addition would be to do that with a partner when you're able to.
Ideally a second charm killer. Preferably an Enchanter to haste the pets.
Forming a group of any size (even just a duo) negates the exp penalty of your pet doing more than 50% of the dmg to an NPC.
Bind @ exp area is also a great recommendation. As a shmuck who quad'ed a Wizard to 60 as his first main, I can tell you that bopping out to grab C2 refreshes dramatically increased my exp per hour when it was available. With C2 I was able to clear both suits camps in WL instead of 1 before repops. Not bad for a Wizardling.
