Quote from Thyede »Several people have mentioned ramp as an issue. I think R/W ramps better than most color combinations that don't include green.
Other areas I'll concede to, but I dont think ramp is a weakness, relatively.
Red has some good ramp. I'd say blue and black also have some. (Seriously, High Tide/Bubbling Muck is a huge deal. Blue can also reduce mana costs and has colorless dorks, while black probably has the most mana doublers.) White? Not so much, but in normal, 20-life Magic, white doesn't need to ramp. Basically, white has Land Tax type effects.
