OK, I'll bite.
(a bit before I start)
I haven't been playing chess competitively for a while, but when I was 12 I got into an East Australian Invitational tournament, and I grew up playing some of QLD's best young chess players, under one of Australia's greatest female chess players (and now I'm in game design, go figure...)
Anyone who would rather have 1 queen over 8 pawns hasn't grasped how useful those guys can be. Used well, they can form an impenetrable line of defense or a secure path for defense. As good as the other pieces are, it's these 16 little buggers that actually control the board. You can use them to decide what side of the board the gam is going to be played on; your side or your opponent's, or kings/queens (left/right). These guys form the 'terrain', if you will, while they can be picked off, their sheer number and their ability to form rock solid formations means they decide the 'where' of the game.
Not only that, but guaranteed 10/10 they'll net you more 'kills' than any other 'class', and the lead only gets bigger if you use the points system many people are now using.
The other 'classes' each work wonderfully together, and it's beautiful watching a unstoppable plan slowly unravel turn by turn as the pieces move cornering your opponent with the precision of a swiss watch.
Any claims of 'balance issues' are only there because the person who said it hasn't grasped the gameplay enough to realize the truth. As in, who you're up against has way more of an effect than what you're up against on the board.
But the biggest, most important aspect of Chess is the strategy. The possibilities, and the execution are areas humans can still compete with machines in; it's that wonderful. inb4 deep blue's revenge.
I'm yet to find a game that's as 'deep' as Chess. I doubt I ever will.
