Currently, werewolf has different animations than a druid and wonky and complicated ways to calculate its attack speed. This also allows for faster possible attack speeds.
Right now werewolf (anim code 40) has animations of:
A1: 13 frames, 256 speed, 7 action
A2: 13 frames, 256 speed, 7 action
S1: 16 frames, 256 speed
S3: 10 frames, 240 speed, 6 action
S4: 7 frames, 152 speed, 4 action
13 base frames for an attack animation is very fast. For contrast, the human druid has
A1/A2 - 1HS - 19 frames, 256 speed, 9 action (1 hand swing weapons)
A1/A2 - 2HS - 21 frames, 256 speed, 10 action (2 hand swing weapons)
A1/A2 - 1HT - 19 frames, 256 speed, 8 action (1 hand thrust weapons)
A1/A2 - 2HT - 23 frames, 256 speed, 9 action (2 hand thrust weapons)
A1 - H2H - 16 frames, 256 speed, 8 action (unarmed)
A1/A2 - STF - 17 frames, 256 speed, 9 action (staff)
A1 - BOW - 16 frames, 256 speed, 8 action (bow)
A1 - XBW - 20 frames, 256 speed, 10 faction (crossbow)
Animations are capped at +75% EIAS after all effects added together, so no matter how much EIAS a skill adds, at some point it becomes redundant. If werewolf attack frames are made equal to druid human attack frames with that much +% EIAS on the skill, and they keep the +75% max cap in place, then werewolf druids are going to attack miserably fucking slow compared to how they do right now.
