As soon as you change a single piece of gear, these all change. With respect to haste specifically, the more haste you get, the more valuable it becomes until 30% (breakpoints are still in effect though, of course). It's an overall change that you really can't see reflected in sims until you get to that point, and that's when haste and crit really start to scale well. This is what makes stat weights so complicated, the fact that they constantly change for every individual character and situation.
Also- the benefits from Haste are much bigger than just what you're describing. It lowers the GCD, and does increase auto attack damage (which is meh to begin with, like you said), but its main benefit is the fact that it also lowers the cooldown of our actual main rotational abilities, meaning you can cast more of them in the same amount of time, meaning more HoPo and directly more TVs, which is our major source of damage. It also decreases the cooldown of judgment, which means more uptime on the judgment debuff and makes target switching slightly less painful (currently it's my biggest conplaint about ret). Those are the main advantages that make it worthwhile, and they cap at 30% becausw that is when the judgment debuff uptime can reach 100%.
