That very well could be. The one really critical adjustment is the Z height, and if that drifts, printing will suffer considerably. Using auto bed leveling mostly solves that problem.
I say "mostly" because if your bed is warping with temperature changes, the Z height can change after the leveling process finishes, and can even create banding in the parts as the bed cycles.
This was a big problem with the i3 because the third bearing was near the center of the wooden bed. I put a dial indicator on mine and it moved down to about -0.5mm during the initial heatup, and then moved up to about +0.2mm as the heat soaked through the wooden part. Colin told me this only happens if you paint the wood. All of my printers are lacquered, so I can't confirm or deny.
The i3v has the wheels out closer to the corners, so it's not as bad.
