I like to use lethal, 50% debuff to healing is huge. Too many times i have had a templar/DK get sniped, fall off horse, get dropped to like 30-40% health and then just pop 2 heals and they are back to 90% and your screwed coz you have no element of surprise anymore coz your squishy. You can just move forward while using snipe so that extra range is kinda pointless.
