I think almost every set in the game has some sort of utility right now but what Wildblood offers tends to be outclassed by another set.
1) Jack of few trades, master of none
The set tries to mix both Bleed and Vitality and also offers some melee capabilities. The weapon itself is good but there’s no incentive to use the rest of the set.
The set as a whole allows you to use Grasping Vines as a Vitality skill with good sustainability and Weapon Damage bonuses, but every time you’re casting Swarm and Vines, you’re not swinging your weapon which leads to a major damage loss.
2) Few skill bonuses and undesirable full set bonus
For taking up both hands and the belt slot, slots which typically hold many class bonuses, the full set does not return a bonus befitting such an investment.
The set bonuses are also wholly offensive but lack some core stats such as RR.
1) Improve the set’s identity
Leaving the weapon stats as is so it fits both a caster and fighter role is fine, but I think the full set should be narrowed down to either caster or fighter.
In the case of fighter, it could have bonuses to Feral Hunger (extra WD/crit, flat Vit damage) or boost Wendigo Totem (improved heal, additional bonuses while totem is up).
If the Vines bonuses stay, it should offer something such as RR or OA/DA debuffs to give fighter builds a reason to cast it before swinging the weapon.
For a caster theme, it should have some RR or significant damage bonuses to be a competitive alternative to established Vit/Bleed 1h items.
2) Pad the set bonuses
To mitigate the skill point drain, the set could use a +1 to Shaman skills in the full set bonus. The 2 set bonus is missing its partner stats of Vitality/Decay % bonuses for some reason as well.
It would be nice if the non-Mythical proc made a return in some way that added some defensive stats too. I could see something such as a temporary 20% life buff fit in such a proc.
Having the Vit/Bleed % damage bonuses return would mitigate some of the weaknesses of using this damage type combo, since several items slots (medal, component) don’t support it well, or give the wrong skill bonuses.
