I'll cut to the chase. Would it be out of line to include a solid bop to the head ala Aegis of Assault? I'm well aware this would dwarf the current assault build in usefulness, but strictly on a balance level, comparing it to other defenders, and not other builds of the Swordmage, would this be in line with most defenders? Personally, I believe it would. The Aegis of Ensnarement is such a fun concept, but it falls lacking so strongly. It doesn't punish. Like, not even a little bit. Ooh, combat advantage for less than a round! Riviting! And what's this? I can take a feat to add a SLOW!? Brilliant! It just doesn't seem to do any defending, so my DM and I are hoping to give it the marked target an actual reason to hesitate attacking someone else, recieving it's teleport, and then shift charging while presumably giving the Swordmage the middle finger.
