Diablo 3 is fundamentally broken

[Quark]

Spiderlings anything is ridiculous for casters. They're too fast to kite, and do lots of "small" damage (the small being relative), where Wizards are built to take a few large hits. Mortar is better than pre-1.0.3, but in the process they bugged it out. Near corners you can get hit by it at point blank range - like walls are cutting into the minimum range for it.
