Suggestion - skill point scrolls
No. Hero challenges are points you CANNOT move to other characters. Afterall, did you expect these to be the only elite specs they release? How are you gonna unlock the others? I mean, it’s also rather lazy that you dont want to put in the effort to use a character enough to unlock it’s spec.
It’s not laziness. It’s boring. As I said, one, two, even three characters, it’s ok. But when you get to doing for the FIFTH time the same exact thing, and have two more to go, it really gets to the “forget this, I’ll just get back on my main”.
If you find it boring, and if wvw is of interest for you, you can spend proof of heroics at the notary to get consumables for tyria OR HoT (1 token or 10 tokens), that when consumed, will complete a random hero challenge and give you the points (not experience though). Just be aware that you need to do this on the character you want the points on, as the proofs are soulbound.
Unfortunately, as I said in OP, WvW is no longer something I enjoy.
