First, the landraiders fire either their assault cannons or multimeltas on the way in, while moving 12" each time. And when BA, BT, and SW disembark tactical squads them move straight into combat since they are in assault vehicles. If they cannot get into combat, they don't disembark. The raiders pop the vehicles and kill what is inside. On kill point missions they brutalize. They stay tight and work in a block.
Now that is on the tavern lets fully derail this.
Land Riders have very little killing power on their own. You get 3 meltas 3 Heavy Bolters and 6 Twin Lass cannons, That sums up the entire Ranged attack power of your army, thats weak man, seriously weak, even for marines. I mean reasons and list that can beat this are too many to sum up, i really have a hard time figuring out, how this army could pose a serious threat, the only way i see this army being anything close to effective is if your opponent sits and take it, trying to beat in your own game.
Also, out of the 3 you listed, wolves have the toughest lines for close combat, and i think you are seriously over estimating the punishment they can take.
Say you rush, and assault a unit and killing with out loosing a single model, then what?, you are considering your riders as such a big asset, but only in 1 mission out of 3 your opponent would actually need to deal with them, the rest of the time he just want them to deliver the payload so he can cripple you. 10 marines are not that particularly hard to kill and even loosing 1 squad seriously gimps your army in all 3 missions. One mission requires you to relinquish 1 assault unit, cutting back nearly 33% of your force. I mean, it is really hard not to see this list weaknesses.
