The fighter weapon table on pg 77 lists Wisdom (and rarely dexterity) as the governing attribute for polearms, this is in relation to powers that work better with specific weapons and grant secondary effects etc. However of the 3 powers that work better with polearms, none of them use wisdom at all, and only 1 uses dexterity:
Dance of Steel, 3rd lvl attack: No effect from attributes
Silverstep, 13th lvl attack: Dexterity determines effect
Paralyzing Strike, 23rd level attack: No effect from attributes
In fact, I believe the only use fighters specifically can get from wisdom is the pit fighter paragon path... unless I missed something.
