You know, all this reflavouring of powers and effects seem rather ackward. Are you guy
saying that if i take the ranger, call it something else and reflavour all his
powers, i could get the rogue i want? Might as well 4th powers be based on generic
power templates and we customize as we want, coz all this reflavouring isn't making
each class powers unique anymore... or they shouldn't be?
Each class role (striker, defender etc) will basically play the same way through
reflavouring..
I am not always a fan of reflavoring, but sometimes I still think people start at the wrong point when envisioning your character.
"I want to play a bow-wielding Rogue!"
I wonder - why this way. Why do you star with bow-wielding Rogue. What's so roguish about your character with the Bow? If it's just that he's good at picking locks and pockets, what's wrong with a Ranger with skill training in Thievery?
What would be the "natural" way of the character to evolve? He is focusing a lot on Bows. In 4E, this means he's probably a Ranger, because Rangers, not Rogues, get a lot of bow-related abilities. Now he's also a Thief, so maybe he just trained in Thievery (maybe via Sneak of Shadows, which also gives you some backstabbing potential). As a Ranger, he is still stealthy and agile. So this character works just fine.
Similar - "I want to play bow-wielding Fighter". Why a fighter? What's so "fightery" about your character? If the Fighter is supposed to defend people, how is he supposed to do this with a bow? Again, doesn't it make more sense for him being a Ranger? A Ranger is the one that strongly trains with the bow.
"I want to play a lightly armored Rapier-wielding Fighter". Why a fighter? Why should someone trained in the arts of warfare not want to wear heavy armor? (Of course, later supplements might bring you a lightly armored Fighter via special class options). But what's wrong with a Rogue or Ranger in this case? I mean, these are the guys whose nature it is to fight lightly armored since their need for stealth and speed requires it. And really, if you're not focusing on stealth or speed, using light armor sounds like a bad idea.
Of course there are other cases.
"I want to play a Wizard that focuses on Illusion, not damage"
Okay - you can't do this with the Wizard class. And no other class, either. So no, your character concept is not supported until the Illusionist class is done. That's suboptimal, certainly at at the moment, your character is not supported. (Though at least you can get the Illusions with the Dragon Illusion spell material!)
Will it ever be supported? I suppose even the Illusionist will want to deal damage - but the flavor might be very different. If the Illusionist creates Illusions that attack people, it makes sense for him to deal damage. Screwing your mind around by creating distracting images - might also deal damage. Creating an illusionary wall - probably won't deal damage.
