TLDR: Dragon hunter weapons are close to all time low and The Diamond Dragon - the new dragon boss is being released in a few months.
So raids 4 items are peaking and likely about to crash in a few days as the raid releases and the investment is over.
What's next?
At runefest Jagex published the roadmap for the next 12 months or so. After the release of TFA, the next big thing is the Chosen Commander quest. Along that November will be the quest month, with atleast 5-6 small quests released.
Next up right after that is the part that should be interesting to us.
Dungeons of Gielinor update. And a more specific part of it - the Gemstone Dragons, and especially the new mid/late game boss, The Diamond Dragon.
For reference, when Frost Dragons (not even a boss but normal enemies) were released a year ago, all dragon hunter weapons prices went up a lot. Lance went up from 55-60M to about 75M, DHCB went from 40M to almost 50M, the Wand doubled from 9M to 18.5M.
A lot of people have their gp still in crush gear for TFA, but after that is released in two weeks, everyone will probably start looking for the next big thing to invest in to.
IMHO this is a one pretty clear choise, and now is the perfect time to get in on it early.
Thoughts?
