Guild Wars 2

I understand I can get these leveling in wvw however I was curious if any of the reward tracks also can grant these? Trying to get a druid as soon as possible and was curious the fastest way of going about this?

Haven’t really played sense about after HoT release so was also curious if the hero challenges are now soloable and gated still?

Honestly it’d be a lot faster to just go around doing the hero points in HoT since each hero point gives 10hero points.
