I find that feat extremely useful.
As a shielding swordmage, I find myself charging a lot more than I thought I would. I'll move close enough to an enemy (move action), mark it with the Aegis of Shielding (minor action) and then charge another enemy (standard action). This puts some distance between my mark and me, increasing the odds it will trigger, and allows me to influence two places on the battlefield at once.
Or if I'm in melee but I'm needed elsewhere, I'll shift away from the enemy I was just fighting, mark it and then charge away to another one.
We also have a warlord, who usually either gives the free attack to me or the ranger.
In this context, Intelligent Blademaster is seeing a lot of use.
