I've really enjoyed reading all of the responses. The original premise of this post was that it was a mistake to put the fix for the Ranger's Hunter’s Mark in the spell itself, and reading everyone else's house rules makes me think that most people agree, as almost all of the fixes are added as a feature of the Ranger, which is where I think it should be too.
The level 13, 17, and 20 Ranger features are another issue, but as has been pointed out, the Paladin gets NOTHING at 13 and 17. So the Ranger features at those levels are better by default. Everyone agrees that the Ranger capstone is bad, but until then I think they are fine.
The level 11 power boost for Ranger comes from their subclass. On the one hand this means that each Ranger subclass will play different than all the other subclass at that level and above. On the other hand, a bad subclass feature at 11 can make the whole class weak in tiers 3 and 4. But I still think it is better than the Paladin that gets the same thing for every subclass. And while +1d8 to attacks is good for damage, it isn't really interesting or fun to play. IMHO.
