OK, having some time on my hands, I decided to create a new set of powers: the lvl 5 daily powers. Readign the wizard powers, I saw one of the banes of martial controllers: a vapoures zone that blocks line of sight ... luckely an idea popped in my head:
Guarding the flank - Tactician 5
Watch out guys! Archers on the left!
Daily - Martial, zone
Standard action - Close blast 10
Effect: You and your allies gain a bonus to defenses against ranged attacks originating from the zone, equal to your intelligence + your wisdom modifier.
Sustain Minor: the zone persists
Flurry of Counterstrikes - Tactician 5
Any enemy that thinks of you as weak and helpless might found himself in sudden loss of blood ...
Daily - Martial, Weapon, Tactic, Stance
Effect: Make a basic attack.
Effect: While the stance lasts, any opponent that attacks you with a melee attack, takes damage equal to the tacticians wisdom modifier
Forced Positioning - Tactician 5
With only a few words, your ally understands where you want your enemies to be
Daily - Martial, Weapon, Tactic
Standard action - Close burst 1
Target: each enemy within burst
Effect: Make a melee basic attack against the target. if it hits you may push the target a number of squares equal to the tacticians intelligence modifier.
