Because melee LB (specially 3) does the most damage of all of them. I really suggest you to look at the wiki to see why that happens.

And this one is a design choice from Devs.
If you have a problem with those, you should suggest something .. better for Devs to take into account.

You suggested DoTs, but people dont like dots, specially keeping them up (check old SMN complains).
