That goes for anyone. If they ever have any questions or comments, just send a tell to Ramblo or Kambing. I'm more than happy to answer questions.
Not sure what your actual question is Arif, but I can write out a mini guide as to where to hunt. I did this back when I was leveling up, but the game has changed quite drastically since then (mainly CC has been removed for tuning).
I would do Miel A over Kaladim at 25. Not sure if you're familiar with Upper Guk, but it's not too hard to get to a good spot to camp. Just go in and left, you'll come to a ladder, go down there and there are plenty of mobs to kill. These instructions suck, but if you're familiar they should help, perhaps.
Miel A will take you to 30 no problem, 34 if you go past the Magicians (which is tough, perhaps try invis).
From 34 to 42, Paw is good. The entry stuff alone will take you to 42. There are problems with getting mezzed and such, but it's still a very good place with a very nice zone exp. bonus.
42 to 54, I went to Lower Guk. You may need a group at first, but once you hit 50 you can start duoing easily. Hell, before that you can duo easily. Just make sure to split the pulls.
After 54, there are a plethora of options that will yield both good exp. and loot. Dragon Necropolis is a favourite of mine. The trash mobs (snakes, spiders, goos, etc) will take you to 60 no problem, and are easy. Labrynth (Velks) may be a bit tough at 54, but the spawn is slow so it really wont' matter. The Deep (very nice bonus, pretty easy to get to) is probably my zone of choice. Plus the Rare Fungus drops some nice loot for both of your characters (depending on what tunic, gloves, and range item you currently have).
The Deep is dark blue until 58, 59. Once that level, I suggest going to Siren's Grotto, the WW side. Kill the stuff there, which will take you all the way to 65.
At 65, go to The Blight. You'll need EB, and that is probably the most challenging part about the zone. It's boring as hell, but decent exp. Get a few AA's from here, then move onto better zones. In fact, you can skip The Blight completely and head back to DN, this time taking out rats. The bottom of Velks (Lab.) is pretty good as well, but it may not be as duoable as you'd like.
Quick easy leveling guide with some ideas. There are a lot more zones and a lot more content out there, but this just seems easy and has his exp. modifiers in most of these zones (minus DN). This was certainly not the way I leveled up, but I wish I had.
