If you're not rushing to top 50 or whatever I'd stay the fuck out of OOT and wait for The Hole to open up. The quality of life in Hole drops and exp per pull versus OOT goblins is big. The problem is you'll need Vox and Naggy dead and that'll take 2-3 days from server launch (probably). The Hole has some rough mobs like golems, but if you have Allure you've got a killing machine that has 4x the DPS of any member of your group and you've got ACTUAL drops worth equipping/trading. And if you can manage the undead tower, you've got bigtime early money from withered leather.
Standard leveling for most people should be newbie zone--Oasis/Crushbone---Unrest/Upper Guk----Lower Guk---- SolB/Hole/OoT. It's unfortunate they didn't mix it up as this cycle is super stagnant, but that's the best bang for your buck. Mangler my group the highest day one outside of a 6 boxer and we did some alt zones like Mistmoore and it was okay, but not worth it. Unfortunately if there's a place you THINK could be a secret gem, it's not. These are the settled meta unfortunately and unless DPG does something next TLP it'll be this way for a while.
I will say for Kunark a pro tip is if you have 1-2 enchanters with allure and OOG support undead tower will take you from 51-54 faster than anything else Kunark has to offer. Partially because of the exp bonus/mob level, but mostly because you just have premium pet opportunities there.
