The X button is not just a shield, its got the trip mine (if you have one) for blowing up warthogs, tanks, etc too. I see what your saying but I could be quite useful in very tight spots.
After a short break from wc and fletching I got back to it and got this I will also be trying to beat Star Wars: KOTOR (no i still have not beat it lol) as well. Had to start the game over when I got a 360 and just started playing again and decided to beat it. So thats another goal of mine just not on RS lol.
After a short break I'm back to cutting willows/yews. I cut some mage's today with a friend; first time I've gone to cut them before. Stats updated too.
