Nah, it's a pretty ok feat, but the cornerstone dual-wielder is the strongest Striker in raw numbers.
Rogues tend to be about mobility, a few attacks (only class with a Minor Action Ranged Attack, plus things like Low Slash and Tumbling Strike), and good controller effects that actually matter (Knockout being an example, but Sand In Their Eyes too). The Wilder should definitely be the sort of "loads of attacks" type of guy, especially because the Wilder PP makes critting easier. It's a nice call back.
>What was your favorite piece of 4e artwork, either in grounds of background, action scene, character art, or even sex appeal?
The Battlemind and Ardents are a big one for me, their art is just so good, but if I had to pick one in particular, Zephyr Blade or Talaric Strategist. I dunno, they're just so damn... attractive.
>What was your favorite bit of 4e lore, and why?
I loved the little stories spread out through the Paragon Paths. The Twiceborn story is great, personally. Actually, I really like how 4e spread out its fluff so you found those little nibblets of stories spread out, so you pieced out the world yourself. Besides that, the Wardens and their circles are just fantastic. Love them, they made a Primal Defender that actually felt different from the other Defenders, and that's kinda difficult to do, honestly. In fact, the Primal power source as a whole felt like that, it's nice that there was some actual separation between them and the others.
>Which races that were either new to 4e or reinvented by 4e did you like, and why?
I'm gonna cheat a bit, and the way the Dwarves were handled was pretty smart in and of itselfm, even though they weren't really reinvented. That said, the one "reworked" race - Gnomes. There was a feeling that, y'know, they actually mattered, they were different from Elves and Halflings and Dwarves.
