Warrior skills: Molten blast & Sunder

Just finished Act 3 on normal. Tried almost every skill at some point during the campaign. These two had me thinking.

Molten blast:
- The first part of the attack can miss quite often when enemy is right next to you. Even with 100% hit chance.

- The attack animation is cool but annoying. It moves the character forwards even if "always attack without moving" option is chosen, or when pressing "attack in place" button. There are situations where I want to attack but keep my distance (and this one is basically a ranged skill), at the moment this skill doesn't let me do that.

Sunder:
Why does it have to be so slow? Even with "Martial tempo" (+25% attack speed) and some from passives, it takes way too long to go through. Especially when many of the bosses are on crack and just move around constantly (for example that fire dude Ketzuli in act 3, dear lord).

And against some ranged enemies, you may be dead before the attack animation is done. For example those porcupine crabs, there are many of them and they shoot like a machinegun.
