I will start by saying that I am in no way amazing at Crucible. I'm decent at best. However, whenever I play Rift I found that I can win the game practically solo just by using MIDA and Blink to get to the enemy's Rift quickly. So far I've won at least eight or nine games using this method. In fact, I'll usually have over 10,000 points by myself and the match will end with Mercy Rule before Heavy Ammo even drops. Again, I'm not trying to brag about my skill in Crucible (I'm actually not that great), but I'm trying to point out a flaw. Whenever someone has the Spark, they should be slowed down somewhat to make it more of a challenge to ignite the enemy's rift, because it's a problem if one person can beat an entire team of six in under four minutes...
