We'll see how it goes with the xp boost and crafting boost
Ask D about how faster leveling helps in the game.

Most Hardcore people are actually the people willing to spend IRL money for things like that though.

Hell I might even do it to try it. It seems to be cheap. someone look it up but I think its like 1-2 dollars an hour or something?

Honestly they shouldn't have added that, or at the very least, wait 2-3 months before introducing it when everyone is already level capped.

I don't know, personally I don't see how leveling faster than other people in this game really gives you and advantage over anybody else. Except maybe WvW, but even then it will be a slight advantage because everyone is scaled to 80 anyways. In 5v5 your character is automatically leveled to 80 and given all of the skills and traits and everything.

In PvE, there's no PKing so you don't have to worry about being ganked by higher levels. If you're doing a low level event your level is scaled down to that event so high levels can't grief lower levels in any way. Likewise in dungeons your level is scaled down to the content as well.

It's about 1.88 an hour which is actually pretty expensive if you think about it. That's around $15 a day if you play around 8 hours a day. Over 400 dollars in a month. Not just that, but it's only from mob kills. Most of exp will come from quests and events. I doubt many people are hardcore enough to maintain something like that which means there probably won't even be enough higher level people to even make an impact in WvW.
