An extra die of damage per tier per turn against one enemy just seems so much... BETTER than all your other feat options.
Consider you'll probably land 4 attacks in a given encounter.
Weapon Focus will then give you an average of 4 extra damage over the encounter. Proficiency with a superior weapon maybe a point more, taking [2W] and [3W] powers into account.
Warrior of the Wild will give you much more average damage over the course of the encounter, depending on how many of those attacks are against your quarry. Assuming you're being sticky and concentrating fire on one foe, that's probably 7 damage at least. If you land all four blows on the same enemy, as when fighting a solo, that's an average of 14 extra damage.
Plus training in a Ranger skill to boot.
At the moment, the only reasons I can think of to not multiclass into Ranger are:
1. You have another multiclass that you want
2. Both Dex and Str are too low
3. You're like so far from being the damage guy
4. You are already a ranger
