I played the same two characters and had a diametrically opposed opinion. The Invoker's Astral Shift of the party to the high ground in round one was considered by the group as the MVP move of the day. The Invoker may not challenge my holy trinity of wizard, paladin and cleric, but it certainly ranks as one of my top tier classes.
Had the swordmage for round two and found it far more frustrating. I enjoy fey step, but if I want a Basic D&D elf, I'll play one in that game.
I'm not talking about the cutesy teleportation stuff, I only bothered using Fey Step in the second fight and only because the duergar cleric had insulted me, my race and my god, so I Fey Stepped over to him, marked him, and whacked him, in cheerful defiance of sensible tactics.
See, the Swordmage, despite having maybe two powers I'd ever take, felt like I was doing my job and I felt actually effective. You want to try to go pound on the squishy? Enjoy your damage you just took trying to leave me, oh and here you are again, did you miss me while you were gone?
The Invoker on the other hand... Meh. The teleportation daily, the pull encounter power, and the one fire attack on the scarecrow thing were the only times I really felt useful. We were constantly too bunched up or too spread out for most of my encounter/dailies to be usable without nuking the party or only hitting one enemy, usually one which wasn't much of a threat to begin with. The pull and the teleport I used to get townspeople off an altar and teleport the artificer with the townspeople away from an enemy, and in the end it was pointless because the party killed them anyway while I was unconscious after I went down after being the only person in a position to keep the unconscious Barbarian from drowning long enough for the Artificer to heal him. *facepalm*
To be fair, I had terrible dice rolls with the Invoker as well.
The problem was that it broke down to mostly spamming the same one at-will with both characters, but while with the Swordmage and Booming Blade that felt like I was actually doing something, with the Invoker and the power I was using there I don't remember the name of that can hit two enemies, it just felt like I was proving a crappy amount of extra damage, and not actually doing anything useful. Sure, I eventually burned through all my encounter powers and dailies in the second encounter, but none of it felt particularly effective in the end.
Maybe I just don't 'get' the class and its role as well as I get Swordmage and its role. The Swordmage didn't feel as effective the second time until later in the second encounter when the guy playing her seemed to get a feel for her and started using Booming Blade instead of the other at-will. I can't say I ever got a feel for the Invoker. It wasn't 'Oh, here's this and this and OK, if I do that...', it was 'Oh, here's a bunch of powers that I don't really see anything to do anything with other than use them if they ever become useful.'
More importantly, the class didn't actually feel like anything. I wasn't seeing the point. Swordmage, hey, gish who punishes people for not attacking him(Well her). Invoker... Uh... Does this dress I'm wearing make me look fat? I spent five hours playing the thing and still had no idea what its schtick was supposed to be, other than 'guy who wears a dress and throws divine magic missile around and occasionally gives stuff status effects. If his allies aren't in the way and he can actually hit'.
Man, as much as they all got clumped together with the enemies do I wish the Swdmage would have had Swordburst.
