Heres my solution.
For wilderness survival, since most people use staffs anyways.. Just give them one. It could be modded like any other staff.
Druid Staff
Energy +10
Nature Dmg: 11-22 (Requires 9. Wilderness Survival)
Two-Handed
To avoid being over powered, bows couldn't just require expertise. As then what would be the point of marksmanship at all for an interrupter? So give them a new weapon with a short range (no matter what) and a fast attack speed but low damage, can be modded like a normal bow. So people would still use marksmanship for the other bow types.
Crossbow
Piercing Dmg: 11-22 (Requires 9. Expertise)
Damage +15% (while health is above 50%
Attack Rate: 1.33
Range: Short Bow
Two-Handed
Beast Mastery has always needed something to make it more effective.. And there are a number of options. Whips seem to be the most popular choice so I want to try and create something original. The axe can be modded like any regular axe,The whip would require new mods, and the charms are basically focus items. The different between the Apache Tomahawk and Tomahawk are that the Apache one is two-handed and deals more damage with a slower attack speed. (basically a bigger axe)
Apache Tomahawk
Slashing Dmg: 8-34 (Requires 9. Beast Mastery)
Damage +15% (while health is above 50%)
Attack Rate:1.55
Two-Handed
Tomahawk
Slashing Dmg: 3-22 (Requires 9. Beast Mastery)
Damage +15% (while health is above 50%)
Attack Rate:1.33
One-Handed
Whip
Lash Dmg: 9-19 (Requires 9. Beast Mastery)
Damage +15% (while health is above 50%)
Attack Rate:1.33
Two-Handed
Charm
Energy +10 (Requires 9. Beast Mastery)
Halves skill recharge of Beast Mastery skills (Chance: 20%)
Halves skill casting time of Beast Mastery skills (Chance: 20%)
