Is this a legal add on? Or what are others using if a auto turn in add on is legal?

So I've been looking into the speed runs for leveling 1-10 and i'm seeing a very similar pattern.. All Warriors. And over looking the classes it makes sense why. They are the most officiant movement wise as they have, level 1 is instant cast no resource needed, and the level 3 is a gap closer. And a higher than other damage out put. So basically making any other class obsolete to compete for number 1 rank.

I think it should be sorted by class as some classes have a clear advantage, so ranking them all on the same playing field doesn't make sense. Having a #1 hunter run, or warlock run would make the the category healthier and provide more than just spamming warrior runs.

Is this a change that can be implemented into 1-10 runs?
