It's a real pity it's core only...there's a ton of great archetypes out there, especially one that solves the whole "Bard works best the more meleers there are" setting: Magician. Got a ton of casters in the party and know (as you should) you'll be hitting SR eventually? Dweomercraft Performance. Need to be better at wands so that you can substitute some spellcasting and have a wider variety of buffs and also make up for your small number of spells? Wand Mastery + Magical Talent. Wanna get some of those awesome buff/utility Wizard spells or get some awesome Witch debuffs? Expanded Repetoire. Only problem? Meleers get no benefit and you lose bardic knowledge. But it depends on the party. Sucks it's only core for his party though :<

One of treentmonk's suggested roles for a bard, btw, isn't just front-line fighter but front-line CC. The whip can become an enemy's hell at range... it's not a bad idea. And while you aren't tripping/disarming/tricking/feinting? Bardic performance, buffs, wands, etc. Personally, I like Bards as the best "Support", not necessarily "Buffer". If I had to play a character that could, as he says, "primarily boost other people's performances &/or protect them from harm", then Bard is the way I go every time. And the best part? You get to write about how well everyone did as well. For those true support hearts out there.

Also just realized this post is 2 years old....*cough*. Well that's my two cents on the subject either way :x

Alright...Here's the confirmed wording on ImpNatArmor which has THE SAME LEVEL INCREMENTS AS THE FEAT. I know that you can only take 1 feat every odd level which means you can't take the feat at 20, but here's where it doesn't matter:

The description of the evolution says, "This evolution can be taken once for every five levels the summoner possesses." Unfortunately, that text is unclear. A summoner can select this evolution once for levels 1—4, again for levels 5–9, a third time at levels 10–14, a fourth time at levels 15–19, and a fifth time at level 20. This wording will be clarified in the next update document and print run for the APG.

Now, whoever started this post, that means you can take the Extra Evolutions feat 4 times based on the level ranges that were included in this explanation of the Evolution, ImpNatArmor.

1st: lvl1 or lvl3
2nd: lvl5 or lvl7 or lvl9
3rd: lvl11 or lvl13
4th: lvl15 or lvl17 or lvl19.

4 times caps at 20. 4 extra evolution points. The devs have made their explanation and so you have your answer. If you don't like it the go make your own rules and stop asking about the dev rules. I know it was unclear, which is what you are stressing, but when they clarified the intent of ImpNatArmor evolution, they inadvertently also cleared up this feat's bad wording.
