Wow, there's an unexpected viewpoint.
Dual wield Rogues is my favorite class to play as the Warden, no contest. So many delicious moves, so many buttons to press, so many cool passives, minimal sustains. excellent survivability, ability to scout ahead, disarm traps, open chests and lcoked doors... Plus you get a shedload of additional and fun quests from Slim Couldry.
What's not to love?
I'll always be in love with DA:O's versatility and class build possibility. Take a standard archetype class like a Rogue, and choose to create a traditional sneaky, stabby melee Rogue, a ranged Ranger, similar to Wow's Hunter class, or break every rule in the book (as I did on my last playthtrough) and make a plate-wearing, dual sword wielding offtank juggernaut that nigh-on impossible to kill.
It's when you consider the above that you realis just how limiting and restrictive DA:2 was in terms of class flexibility... and then DA:I makes even DA:2 look like a paradigm of flexibility and versatility, as in that game I'm locked solid into a rigid template that cannot be modified or experimented with.
I wish Bioware would get it into their heads that most players enjoy experimenting with different builds and options, and prefer not to be railroaded into a narrowly-defined class template.
