In one of the first announcment on the converting of skill-points to hero-points Anet has given the idea that someone need to explore a certain amount of hero-challenges to unlock all abilitys and traits. (see: https://www.guildwars2.com/en/news/specializations-part-two-reward-tracks-and-elite-specializations/ ) Short before the patch with the core-specializations hit, they announced that you will get enough hero-points trough leveling, that you can unlock all core-features at level 80. (see: https://forum-en.gw2archive.eu/forum/game/gw2/Skill-points-and-Spirit-Shards/first#post5187859 )
This was a nice way to change things and before the second announcement there were many critical voices who wanted too play for example WvW without bothering with map-exploration. Now everyone with a certain amount of map-exploration has a stockpile of (atm) useless hero-points and the community is speculating if they are for the new specializations and there utilitys. And I think these speculations are right. But I fear they will bring back the critics from people who like to play WvW only or people who do not enjoy map-exploration, but both groups of people will enjoy or maybe need one or two of these new features. And this is the point were my idea begins.
At the core its simple: Why not buy the heropoints?
The heropoints will be limited trough the number of hero-challenges, so simply buying 5 or 20 or whatever number wouldn´d do the job. So the NPC who sell the hero-points should not sell blank points, he should sell the points from the maps. The idea is, that you could go to the NPC select maybe “Caledon Forest” and get all hero-challenges of this particular map done aka you gain the exact amount af 7 hero-points the Caledon Forest has to offer. Should you has done maybe 3 off the 7 hero-challenges you will get simply the rest done aka you get the rest 4 hero-points.
What could be the price of this?
My suggestion would be 1 gold per hero-point. So in example of the Caledon Forest it will cost 7 gold to unlock all hero-challenges on this map. If the specialization tracks cost the same amount of hero-points, then it will cost 60 gold to unlock the full track trough this methode. In my opinion a fair price, but sure a point we can discusse about.
Will this affect the world-exploration?
I think not. Buying all hero-challenges for world-exploration would be 189 gold if you follow my price-suggestion of 1 gold per hero-point. And at this point the person gets only the challenges done, nothing more. He or she has to run the entery map for the rest of it and I doubt a normal player would invest such a amount of gold only to spare maybe an hour for the full world-exploration.
After going this trough my head a second time it seems as a reasonable idea. With this a full fletched WvW-Player will get his hands on enough hero-points to unlock all he wants with gold. Someone who dislike map-exploration can choose if he wants to spend the gold for the points or bite in the pillow and go trough the exploration. And people who likes exploration could ignore this.
Last but not least I have no idea how hard it would be to implement something like this. Furthermore I have no idea if there should be a fix price for every map (like 7 gold for Caledon Forest ignoring the fact that you might already have 5 of the 7 hero-points) or a dynamic one (like to unlock the last 2 hero-challenges cost you 2 gold).
