Good thing this FREE world tour.
But 400k usual price?
Let's see who has that sort of money:
1) People who played the game before and farmed alot. As a result they made friends, maybe joined a guild. And overall, they KNOW how to play this game. Result, this category will not accept an overpriced "tour" like that, IMO
2) New players who bought money with hard cash (ebay, etc). IMO if they pay for this service they miss everything what makes the PvE part intresting and worth playing. IMO this is just like a winning maraton by getting to the finish line by car... has no sense. So even if these people will pay, they'll either leave the pve part after some days, weeks of playing because they`ll have no fun in it or they'll smack their ead against the wall when they realise what a waiste of money it was.
Other solutions: use diffrent runners to reduce cost.
Ascalon - Beacons (can be split in more steps, like Asc - Piken, Piken - Yaks, Yaks - Beacon), total cost between 2-5k. Becaons - Droknars run is between 3 and 10k depending on how patient you are, you might get it for free.
Total cost to get to droknars till now doesn't exceed 20k.
For 300-1000 you can get to LA. From LA to ToA same price, 1k being the upper limit.
From toa to Sanctum Cay you can be charged between 1 and 3k. Cay mission run is like 1k.
And your in Amnoon Oasis.
Till now, you have Droknars and Oasis all for like let's see, a 25k total expense.
Now, you need to get to Augury. I don't know how much this might cost, but let's assume 5k max price. From augury for another 5k you can be ran to all places in the desert, you might get everything for as low as 1k, depending on the greed of the runners.
Till now, having every place in the desert along with droks and you spend like MAX 35k.
Thirsty being the hardest mission to run, it will cost you like 5k. The remaing 2 will cost you MAX 5 all together.
Let's see now... You can now try and ascend for a total cost of 45k (upper limit). If your smart, lucky, know how to negociate, you can spend maybe 20k less.
Let's assume the everything you've done till now is only HALF of the so called "world tour". How much did you save? Like 155k? You can spend now 20k on a droknars armor (buying everything from mechant).
If you have time to spend testing your new armor, you can level up and try beat your dop. If you are building a mo/* for farming, you can beat dopey at lvl 7 without problem having the right skills. Just do a search to see the most effective way to beat your dop with diffrent professions. And since you probably stopped in many places with skill trainers, you can buy the skills for cash (Ascalon, Yaks, LA, Fishermans, Amnoon, Droks, Camp Rankor).
If you manage to ascend.... weee... quantum leap in XP. 50.000 XP power level you quite good. You should be between lvl 14-17 now.
From this point on, you can go and do the easiset missions and the quest with high XP. Also, do the sardelac, yaks "skill reward" quests to have some skills you can use.
I`m too lazy to type prices and stuff for the part that concerns post Droknars, but for like 20-25k you can get to all places in shiverpeak, and also get to the ring of fire, become lvl 20, etc...
So this whole "world tour" (in case you pay it) is a big ***** IMO.
EDIT: i know what i typed
I've seen that it's a marketing strategy (offering the service for free) of the OP. I`m only expressing my opinion regarding the usual price.
