Feral has the lowest number of choice talents as well as nodes overall on their tree out of the Druid specs, so there’s definitely space to add things. I went through and looked at our old borrowed power. Here’s a list of things that could be brought back from previous iterations of Feral, changed if needed and placed on the trees.
Incessant Hunter - Rip damage has a X% chance to grant 3 Energy.
Wild Fleshrending – Shred deals X additional damage, and Brutal Slash / Swipe deal Y additional damage to enemies suffering from your Thrash.
Ashamane’s Rip - Your combo point generators against targets bleeding from your Rip have a 10% chance to awaken the Spirit of Ashamane, which inflicts a Shadowy duplicate of that Rip on the target. (On Beta it procced from Bites)
Jungle Fury - Tiger’s Fury increases your Critical Strike by X and lasts 12/17 seconds.
Mangle (Cat) - Mangle the target for X damage and causes the target to take 30% additional damage from bleed effects for 1 min. Awards 1 combo point. (Could make it one target only to be used as priority target damage)
Chatoyant Signet - Increases your Energy regeneration by 5% and maximum Energy by 100 while in Cat Form
Ailuro Pouncers - Gain 1 stack of Predatory Swiftness every 15 sec. Additionally, Predatory Swiftness now stacks up to 3 times.
The Wildshaper’s Clutch - Critical damage from your Bleeds have a 40% chance to trigger Primal Fury.
Behemoth Headdress - Finishing moves extend the duration of Tiger’s Fury by 0.5 sec per combo point spent.
Luffa Wrappings - Increases the damage and radius of Thrash by 75%.
Feral Power - Increases the critical strike chance of Shred by 5/10/15%.
Hardened Roots - Your Bleed damage will no longer cancel Entangling Roots early.
Shadow Thrash - Thrash has a 25% chance to release part of Ashamane’s soul, causing all nearby enemies to take Shadow damage over 2 sec.
Not a talent or anything, but Emerald Nightmare Feral had really low resource generation and crazy good dots. Maybe do something to bring that gameplay back. -50% energy regen and gain, +25% dot damage?
