Mangos version: 10050
How it should work:
With maximum weapon skill your glancing blow damage against mobs 3 levels higher should be between 65% and 85% of your normal damage.
In patch 3.3 the glancing blow penalty for casters was removed, now every class has the same damage penalty from glancing blows:
How it works:
The glancing blow damage of druid, shaman, mage, warlock and priest is between 1% and 45% of the normal damage.
The glancing blow damage of other classes is between 55% and 75% of the normal damage.
I wrote a patch that modifies the following:
* Removes the glancing blow damage penalty for druid, shaman, mage, warlock and priest. * In the elitistjerks forum (http://elitistjerks.com/f73/t36999-feral_druid_numbers_updated_3_2_2_a/p2/) testing with a druid the glancing blow damage was between 65% and 85% of the normal damage, in the code there is an upper limit of 60% in the low end of glancing blow damage for classes other than rogue and warrior. The patch sets the upper limit of the low end glancing blow damage to 91% for all classes. * Increases the minimum and maximum range of glancing blow reduction by 0.1, so the glancing blow damage will be between 65% and 85% of the normal damage against bosses. * Removes the check of minimum range > maximum range because it is always true.
