I'm the elven ranger, and I have to say. Missing with your daily is frustrating. It's your most awesome power, dealing tons of damage, but if you miss, it's still gone. It would be nice if some of the Ranger's powers were reliable.
On the other hand, minions provide an important detail point: Never bother with anything more than your daily powers against them, since they've only got one hitpoint.
I did like having a lot of powers to use. Every turn it was, "which power do I want to use now?"
Also, I did get hit, once, by a kobold javelin, in the first encounter. In the second one, I didn't touched at all.
