First off, I wouldn't be using a Life Orb on this thing. It's purely physical attack-wise, and it would be negating its strong physical defense. What exactly stops 'Mence and Garchomp, anyway? I don't pay much attention to what goes on as far as the D/P metagame because I don't have it yet. Personally, I'd slap a CB on it or go with a seeding set.So you want to take recoil damage from wood hammer and life orb damage at the same time? That is assuming you can actually tell when someone will have an ice attack, which you really can't what with everyone being so scared of Garchomp and Salamence. Those two survive because of their ability to swiftly nail things in one shot. Torterra doesn't have their attack or anywhere close to their speed, so the same stuff that's designed to stop Garchomp and Sala in their tracks will murder it.
I'm not saying it's OMGWTF Awesome, I'm saying that its weaknesses are exaggerated and not much enjoys its STAB attacks. In fact, the biggest problem I see with it is that 'Mence can switch in on it without much trouble, as it resists or is immune to its strongest attacks and Intimidate screws its offense.
