Luck isn't just a matter of taste. A sufficient luck element makes it practical for players of different skill to play together (particularly for 3+ player games, where being uncompetitive isn't so much educational as boring and game-disruptive). Too much luck is unsatisfying for high-skill players, who want close games to consistently go to the more skilled player.
