Wow. After getting 70-75 construction in 2 hours (this took me 3 days runecrafting), I can safely say it's pretty damn fast.
Once you get into a routine of removing oak dungeon doors, adding them again, paying the servant to get you more planks, it's amazingly fast xp, 1200 per door!
Also, I like how each new level gets you at least 3-4 new items to build. Unlike slayer which only offers one more monster to kill after 90...
Should get 80 tonight, then mine for a bit.
