Raid encounters encourage Min/Max.
Unless you specifically design a raid to be punitive to glass cannons who fail to spec into survival or damage reduction, it will eventually boil down to cookie cutter builds that are spreadsheeted and live tested to push the most DPS/Heals in relation to gear.
It's honestly only a matter of time before this happens. Now that people are more actively using parses to check dps I can already see my guild going back to the familiar road of min/max no tolerance rule.
The second I hit 50 and have the gear the first thing I'm going to do is start testing specs out on dummies because I really just need to know what will do the most dps.
The complaining about it has certainly already started on the forums. In the eyes of some, the "elitists" have been ruining the game since before it was launched. And it's the same old arguments that have been put forward for years.
Oddly enough, when the game was in beta testing there was a substantial controversy over whether or not Rift would support addons. For many, "addon" is synonymous with dps meter. The devs made a statement regarding addons and their position was that they didn't want to put forward a mediocre API that would lead to all kinds of issues including addons that trivialize encounters, addons that cause issues with system resources (memory leaks, bloated requirements, etc.) and addons that would cause gameplay issues (buggy addons causing crashes, etc.)
Somehow, the anti-addon crowd saw that as Trion stating that they would not be supporting addons at any time, yet around the same time they made that statement, the devs added the /combatlog command to dump combat logs to a text file. Well, when the anti-addon crowd got word that people were running external parsers...amg...the rage and demands to ban the "cheaters" were relentless. It took several weeks of linking statements directly from the devs saying that addon support was, in fact, under development, etc. etc. before the majority of the anti-addon folks finally shut up.
I'm already seeing people showing up to T1/T2 dungeons with builds that boggle the mind. I'm all for freedom and an opportunity to be a little creative in building your character the way you like, but at the end of the day it still comes down to the numbers and not every build will produce enough of the right kinds of numbers to allow a group to succeed. I've had so many warden clerics insist they can heal T2 dungeons by themselves that I'm now forced to wait for bodhi to build his cleric as a warden and come here with a build and a method and prove that they're capable, because none of the ones I've had trying to heal me have been up to the task. I grow weary of listening to people drone on and on and on about how awesome their build is and they can do this and they can do that and when it's crunch time and they actually have to perform, it's just a big ol' pile of mediocrity that doesn't get the job done.
Funny how it works out, though, because the most mediocre performers are the ones who are the most militant and assertive in trying to force their way of playing down everyone else' throat. I just do my thing. I do okay at doing my thing and I love learning new ways to do my thing that let me do it even better. But gawd help me if I ever suggest to someone that they aren't performing at a level that would allow the group to succeed. Who needs objectivity when you've got indignant rage?
