I've seen more and more posts, in every section, debatting over skill trees, multiple specs, uniques stats on certains items, etc..
And, every time, someone point out that it absolutely wouldn't work because of optimization.
Let me tell you that this is false. Well, not false per se, but absolutely without consequences on the game.
First, let's see the current meta. As you probably witnessed in several threads, most people bitch about one job or another, complaining that it's better/more optimized/more easy, etc...
Yet, every job is still played. You'll see plenty of people claiming that, in order to clear Alexandre Savage, you need to be this tall...sorry, your DPS needs to be this high.
And, not having set foot in Savage yet, I'll believe them...but what about the next month ? Or the month after ? Where everyone will have better gear to match the DPS/Healing/HP check ? Will it bother them torun a non optimized setup ?
Let's say you could spec you BLM a Frost Mage, doing around 20 or 30% less DPS than Fire Mage, but putting more debuff. Who will care when, by being full ilvl220, you'll be doing 40% more DPS than people will do now not being full 190 ? Will you be taken to savage now ? Probably not ? Will you care since you obviously want to play for fun and not for competing at world or server first ? Absolutely not.
The same is true for items. Yoshi-P said he wouldn't make exclusive bonus, fearing that these items would become mandatory. But items would already be mandatory if you want to be optimized. Back in 2.5, Relics Zeta were the absolute best weapons. Yet, people would still clear content without wearing one.
People need to realize that true hardocre raiders only represent a minimal part of the community. Why refuzing something because 5% of the population will use it to create their setup ? Besides, even those people will have fun theorycrafting about what spec is the best for each job, of what item combination gives the best results.
The other 95% will just play what they want to play and wait to overgear (or Echo) the content to clear it the way they want.
