The difference is, it doesn't take a whole lot of manual dexterity, muscle memory, or quick reactive thinking to be competent in a tank. A decent flight simulator, not so much.

No, but arguably being a good tanker is almost as hard. You need to be more aware of your surroundings at all three levels, you need to be able to quickly judge range, and have some sort of 'feel' for where the enemy is likely to be. And frankly, you need to be more clever in a tank; its the sneaky bastards who park their rust colored T-34/85s next to the rust colored barns that will do the best.
What WoT has done is simplify that down to heavily assisted SA, and an assisted feel for where the enemy is.
WoT graphics are not poor. They are not stellar, but far from poor.
Ehh.... they just seem a tad stylized. Hard to point things out in specific, theres just a feel to them; some of corners seem a bit rounded, perhaps some lines seem slightly curved when they should be strait. And really, the metal just doesn't seem quite like metal; something to do with how the light plays off it makes it look more like textured and painted ABS at times. And the color is just too... vivid.
Its clearly not meant to be an accurate portrayal of reality, its meant to be an impression of a specific part of reality; bright vivid terrain, hot sandy desert and exquisite pastel sky, or grey rubble-strewn streets and confining overcast as the back drop for clanking low-profiled machines, flying splinters, fallen trees, destroyed houses, and firey explosions.
