OK...just a guide on how to do it at a low level.
The main problem is just getting there. Easiest I think (and I did this at 14) is to get a trash pet and run, using Beast tracking, from Loch Modan to Menethil in the Wetlands. Give the crocodiles a wide berth! There register with the wing rider and then go to the left jetty and get the boat to Theramore...you can also get a boat from Menethil to Auberdine and Darkshore...good pets there too. At Theramore register with the wing rider and also make the Inn your home. Now run back to the shore and go left between the castle and the water as far as you can. Take off all your kit (except your shirt of course!) as (a) it wont protect you against anything in the water, and (b) you don't want it to take hits anyway. Now using Beast tracking and Humanoid tracking swim south along the coast and between the islands. Remember the yellow titled animals like the tortoises are safe...but the sharks and murlocs will kill you in a couple of hits so give them a wide berth. I run along the beach at first cos the tortoises are fine...and the coral sharks in the water are dead fast...but I keep animal tracking on as there are murlocs ahead. Swim between the islands...avoid the bay halfway down that has a wrecked ship in it...its full of murlocs. If you die you rez at Theramore...just run back to your body...rez and swim on. Eventually you'll come to THe Barrens and Horde Territory in big red letters. Keep going and swim on as close to the deep blue water as you can without getting fatigue. You'll swim past Northwatch Castle (the soldiers there are Ally friendly...but theres usually Horde players attacking them)...keep swimming on and you'll come to what is like a shallow bar between the land and an island where briefly you run rather than swim...it means your getting near Ratchet. To your left the land will recede back into a bay. Swim into the bay looking out for the Makuras..they will likely get your pet as you swim into Ratchet coming to the land to the left of the pier. Ratchet is neutral of course but watch out for Horde...ideally you want to sneak in when theres no one about. If you've succeeded then find a house, keeping to the left side of the road leading up the hill out of Ratchet. You want a house with an upstairs. Theres 2 I think...one by the graveyard where you rez in Ratchet and one closer to the shore. Go upstairs and provided no one has seen you you'll be pretty safe. Get dressed, rez pet and feed up if necessary. Now your in the Barrens. Keep humanoid tracking on...watch out for Horde at all times cos you are way vulnerable here...but you need your armour on cos you can fight off most of the animals at least now. Right when theres no Horde about, jump out of the window and run across the road towards the hills to your lefy as you cross the road past the goblin bruiser. Come up the hills and turn left skirting around past the raptors, hyena and lions. You'll see a tree after a little way with lions and cubs around it. This is the tree where Humar the Pridelord spawns (level 23...dead good pet). Go past this still keeping to the edge of the plateau. Now you need to run across the plateau or plain to the mountain with the ridges coming down. You'll see a ridge with a thorn root going across it (about halfway up) theres usually hyenas between you and this ridge about level 16. Run across up the ridge, jumping over the rooty thing, up to the top. You can see the X roads here to your north. You need to skirt round this so go east and look down to the bottom of the mountain...you want to run back down a ridge that has no roots going across it that lies between a ridge either side that do have roots. You'll see what I mean when you get there. Come down and avoid the Razormaine patrols. You will see a road in the distance and beyond some hills. You need to get across this road without being seen by any Horde players. Across the road you'll see a tree and to the north of it a house. Skirt round the tree and house to the hill and you'll see in front of you some bones sticking out of the ground. This is where Horde players call Echeyakee, a white lion...also a cool pet if you can get it! Go north west round this hill past some trees...till the road north out of the X roads comes into view. Again watch out for Horde players..look towards the road and you'll see to the west that theres a two trees one each side of the road...the thin tree is your side of it and the fat tree the far side. Now if you run towards them you will see framed in them a tree further away. This finally is the tree where Dishu spawns. The tree lies encircled by a hill and is ringed by lions. Dishu spawns amongst them. I usually climb a little way up a ridge and then if shes not there..log off and on till she appears. When she does...kill off the other lions around her first, abandon your trash pet, take any defense potions etc you have and tame her. She will spawn cubs half way through. I've always managed to tame her before they kill me and she then turns on them...but you can try the running way when they appear and going back hoping they dissappear trick. Then feed her up and HS out with a very cool pet. She hasnt the fastest DPS its 1.5 but she looks so good and her chase speed is better than the Durotar tigers who have a DPS of 1.3. Incidently if you want one of those...keep swimming round the coast past Ratchet and you'll come to the ECho Islands (to your right). Durotar tigers are on the Echo islands...easy to tame at level 7 and 8.
Good luck all!
