Ah. You're talking about the tripmonkey spiked chain crusader. Outside of that single archetype, Thicket of Blades isn't all that good at dissuading enemies from attacking your allies.
I dunno, it seems pretty nice at low levels. It definitely wants to get swapped out by middle levels, though. Also depends on party composition and number of physical attackers (but then, I guess that's true of most of White Raven).
