What? X-force's green is his best move. 4k+ damage for only 8 AP? That's enough to make hood a non-issue if you boost
5/5/3 is the only build, the damage on his yellow even @5 is pretty marginal, and 3 is already quite sufficient healing
X-Force - Green 8 AP
Wolverine unleashes his berserker rage, cutting with his adamantium claws. Deals 164 damage and destroys 5 tiles in a 3×3 X-shaped pattern. Does not generate AP.
Level 2: Deals 465 damage.
Level 3: Destroys 9 tiles in a 5×5 X-shaped pattern.
Level 4: Deals 1030 damage.
Level 5: Deals 1731, then destroys 15 tiles in three 3×3 X-shaped patterns.
Max Level: 3441 damage
Surgical Strike - Black 11 AP
Wolverine attacks with ruthless precision, crippling his enemy's ability to retaliate. Destroys every tile in the enemy team's strongest color, dealing 32 damage per tile. Does not generate AP.
Level 2: Deals 87 damage per tile.
Level 3: Deals 137 damage per tile.
Level 4: Also reduces enemy AP in their strongest color by 10.
Level 5: Deals 265 damage per tile. Destroyed tiles now generate AP.
Max Level: 522 damage per tile
I don't know how you can compare those two and say that green is better than black. Black at 270 does 522 damage per tile destroyed, generates AP for every tile destroyed, and reduces their AP in that color by as many as 10. It also has greater potential for cascades by the fact that it completely eliminates a color from the board. It cripples their offense, and can potentially do MORE damage than green can. Also in a situation like mine, where you aren't going to level him to 270 in order to avoid screwing up your PvE level curve, Black becomes that much stronger. It may be 3 AP more but the potential pay off is far higher. Even if you only destroy say, 4 tiles with the attack, that is still 2088 damage to one target, you generated 4 of that color, and you drain as much as 10 AP in their strongest color which can be a huge hinderance if they are going for a Call the Storm/Sniper Rifle/Rage of the Panther or other high damage high AP move.
Overall I agree with you that 5/5/3 is likely his best build, but to me the most important thing to have is the 5 covers in black, the rest is ancilliary
