It's a reach-build, the idea is to keep enemies away from you. Polearm Gamble's probably not the best fit, that one's better for a Fighter cause of their ability to stop enemies with their opportunity attacks.
However, where the reachwarden shines with reach is when it gets combined with Nature's Fury, allowing them to punish violation of their mark over a distance competitive with paladins.
Okay thats a whole heap of issues brought up in one short commentry.
If possible could you give a more detailed reply and explain fully.
Polearm Gamble for me, was to get heaps of OA's against all the enemy I was tanking against, plus extra attacks and epic 19-20 crit to maybe get Holy Blade working to spend a surge on a crit, poss opening up a few build options in other areas.
Plus with Sudden Roots and difficult terrain etc then it will do the same thing as a fighter and effectively stop them.
Yes the key aspect of warden with reach is Natures fury from level 1 being able to stop the shift 1 and charge someone else.
And latter up to reach 3,4, poss 5.
So I dont see a reach build being about keeping enemies away from you, as a Warden or tank wants to keep enemies close to him.
But a reach build can be used to get in a lot more attaks, and attacks that slow.
is there anything you can add to opportunity attacks.
As with the Threatening Reach, there would be eaps of em.
