One of those looks like a correct ruling: nothing is stated about save DCs or the like.
The other looks like it's only minimally considered. To me, there's one reading that has zero effect on the game (ie - that only proficient saves get the bonus) and one reading that actually has an effect (ie - that the requirement for proficiency is limited to skills, not saves, so all saves get the bonus). I'm going to go with the reading that actually has an effect.
Which means that they're not using any other concentration spell. Should we compare a BM ranger using conjure animals to a hunter using hunter's mark? Or perhaps one using pass without trace? Or beast bond? It's hard to say. Comparing "base" attacks is hardly being willfully and maliciously misleading though.
Exactly right. That's why you need to compare base attack to base attack, because there's many different optional factors one could use or not use, and that's what's actually disingenuous; to compare a ranger with hunter's mark v one who happens to be doing something else as the game dictates.
We are having a similar issue with our small group. One of our players wanted to be a Ranger, he liked the feel and role. But we are at the middling levels and now most of the time when a battle is about to begin all he does is try to hide, or even run away. In his mind he is such a wuss that these are realistically his only options - other than presenting another target for the bad guys. He'd rather hide or run away, than force the Cleric to expend all of the party healing on him every encounter.
This is most certainly a player issue that has nothing to do with the class itself.
