Heres my breakdown of where I have leveled all my toons.
0-10: Whatever starting zone my race is.
Dungeons: Starting race dungeon.
10-20: Go to Veskal's Exchange in Thestra do the quests around there and you should be about level 15 then start the URT(United Races of Telon) Which is a great way to level up and get really nice gear. After URT questline you should be at least level 17 and you are ready to head to Hunter's League questline. You'll need a group for this but the rewards are amazing for your level.
Dungeons: Both Spider Caves in Veskal's Exchange. And Kassandra's Coven which is part of the Hunter's League questline.
20-30: Finish up the Hunter's League questline which should lead you to Skrawlra Rock. By the end of that you should be at least level 23. At this level you can start CIS(Coterie Infinieum Sanctuary) questline inside of Qalia. It is a very long and rewarding quest and ends up with you obtaining a legendary weapon. While doing this questline I recommend you going to the Shildreth Mining Company mines and farming a Veline Veil which has the activated ability to turn you into a black panther. After the CIS questline you should be at least level 28 and you can now do River Valley quests which is one chunk west of CIS. I recommend you stack every quest until you've got around 30 or 40 and popping and 100% exp potion and gaining a few levels. After River Valley you should be about 30 or 31.
Dungeons: TK(Trengal Keep) has a long questline that is full of experience.
30-40: After you finish River Valley I suggest you go to Cragwind which is in Qalia and start the quests there. There should be around 25 initial quests and after you do all those and turn them in it should yield another 20 or so quests for you to do. This should get you to about 34 or 35. Now go to Southwatch and do the bounty hunter's questline which is quick and easy armor along with a pretty good exp gain. This should get you close to 37. Now go to Bernard Hills in Thestra and do every quest there but don't turn them in quite yet. Now go to Plains of Anguish and do every quest you can do there. Then pop an exp potion and turn them all in(Should be close to 50 quests). This should get you 42+.
Dungeons: VT(Ruins of Vol Tuniel) Is a great place to make some easy exp. Dargun's Tomb is a great dungeon which has a questline for a legendary weapon which is worth the questline. Graystone is for higher 30s and has a questline to collect Bloody Insignias and it also yields a legendary weapon.
40-50: After you do Plains of Anguish you should be at least 42. Now go to Razad which has quite a few quests for you to do which get you to about 44. Now go to Deadbog and do the quests around the town Ruin Fall and pick which of the 3 factions you want to be aligned with and start farming totems for that faction with the quest from each factions respected emissary. After you collect about 500 or so totems pop an exp potion and you should go straight to 50. And have enough rep to get your faction armor.
Dungeons: In Razad there is a dungeon called Tricksters Haven which has lots of quests and great exp. At about level 46 you can start doing ToT Medal Runs(Which is in Tehatamani) which will yield lucent medals which you can turn in for some of the best jewelry pre APW in the game. You could also do some Hegnerian Runs(6 hour lockout) in Swamp of Rumog which can get you some great items.
Thats just a quick layout I did without using any references so if anything is misspelled I apoligize
I could make a very in depth leveling/ interesting things to do guide in the future with much better formatting
If anyone is interested in me doing so leave some feedback. I don't know if someone has already written on in the premium forums.
I hope this helps anyone who needs it.
Cheers!
