As far as the whole primal tempering thing goes, it was hinted at during the original 1.0 storyline that the mere presence of a primal seethes with corruption, and even those with the echo are advised not to remain in their presence for long. Those without the echo can supposedly succumb to this influence rather easily, but primals do have other means of tempering. Gonna spoiler the primals means of tempering, as some are sort of spoilery?
That being said, Square Enix explicitly went out of their way to establish the Echo as a "common" (not common) gift. In canon, many adventurers all saw the same dream as your character, and many bear the echo. Storyline stuff below.
It's more than acceptable in canon for characters to have the echo, and it's generally the easiest way to go about allowing your character to battle the primals without fear of tempering. As it stands, our characters are the extreme minority in Eorzea, so even if there's a couple hundred roleplayers with the echo, that's about how many might have it in canon. Also, just because your character has the echo doesn't mean it has to come up constantly in roleplay. My character has had the echo since his inception way back near the launch of 1.0, and not once has it ever really been used in his roleplay. It's just something he has and is aware of, and it's something that allows him to help combat the primal threat alongside his fellow woken ones.
As far as it goes, primals are summoned constantly, and this is touched upon in-game. It's technically why we're able to fight them over and over again. It's by no means out of the question for multiple groups of adventurers to have bested a primal, simply because the beastmen just re-summon them when they can.
Lastly, some summoner storyline stuff.
