I've used all of the subclasses, maxed them all out(I have a lot of free time XP) and have used all of them extensively in the Crucible. of all the supers, FoH is the easiest to get kills with, and the grenades are stronger than any others. Yes, its fun using a noob class, but one can only take so much easy kills before one gets bored and goes back to my real classes, my warlock namely. You want to know WHY there aren't as many titans in the top 100? Because the striker class is boring and too easy to use for most hardcore players to take a liking to. And in case you didn't notice, I never mentioned base health on crucible, I said the Titan took less damage during his super. All subclasses take reduced damage during their super, but the most extreme is the striker, bladedancer, and sunsinger, because its easiest to notice when their super brings them close-range and they can't get one-shotted except from rockets or supers.
