demolisher to bad in 8.45 ???

[Tribulation]

It is not useless, it just almost has to be upgraded now to be somewhat effective. The alternative would have been to make the basic version more expensive, but then you would not have been able to afford it right away in combination with Demolisher, so the approach taken was the best solution. Due to its high hp, powerful mines and awesome farming performance with the Multi Bow, the Demolisher was too strong before the Bow was nerfed.

To sum up: the bread-and-butter skill, the mines, are still strong (although the cd and mana cost is higher), and the hp remain high, so the only real nerf the Demo has experienced is its ability to farm.

P.S. The Bow's at 75% now ;-)
