Beastlord

Beastlords can have BP from cotf which got Invorating topor, is that click not complete useles, because you do get 1200 in mana regen per tick and it last 5 ticks.

But you also loss 25% melee speed.

Should you not use any other bp clicks than this ?

That sounds pretty useless to me.

1: Decrease Spell Damage (Before DoT Crit) by 25%
2: Limit: Effect (Skill Attack allowed)
3: Limit: Effect (Hitpoints allowed)
4: Limit: Instant spells only
5: Limit: Spell Type (Detrimental only)
6: Inhibit Melee Attacks by (25%)
7: Increase Current Mana by 900 per tick

Sounds like a med booster. Click it if you were going to sit down anyway, but otherwise seems whack.

Definitely not worth it now.
Group gear ToL BP adds 8 DD procs for 83,706 damage to you AND your pet.

Description on bp says slowing the melee attacks by 25%
not worth with todays mana
