The T'au would have been broken by an event of similar scale to the devastation of Baal, or the plague star shit the Ultramarines have to deal with. The only reason they exist is story contrivances and plot armor of similar grade to Cato Sicarius himself. Their mecha would be impressive, but then you consider that the greatest enemy in the setting isn't particularly effected by guns, and are more so effected by sword and flame. Nor is their technologies, because the necrons are so technologically advanced that that their technology looks like magic to the ignorant.They have really, really big guns, and more to the point, unlike the other factions they can reliably mass-produce them. If even a low-level Warhound Scout Titan gets taken out that's a massive loss representing years of labor. Meanwhile the Tau can and have wiped those out with a single lucky alpha strike from a modified Tigershark. On a rather more practical level, how easily can the Tau replace a couple of Stormsurges and their crews versus the Knight they just gave their lives and war machines to take down? Or a Stormsurge versus a Baneblade? For better or worse, there are no true irreplaceable relics in the Tau arsenal from a height of power never to be regained. They're still on their way up in the galaxy, and they're being smart by taking advantage of the fact they're small fry to steadily expand whenever someone gets distracted.
Also, having a single, big badass that can't be replaced is just as dangerous. Even if takes the simulated deaths of 80 Space Wolf Terminators to down a Primarch in mock combat, that's still a net win for the Rout.
The one time in recent memory they actually spent anytime in the warp, they all went as nuts as lorgar, they couldn't cope whatsoever.
If the hive mind every had a reason to actually go at them, or chaos, or the imperium. They would fold immediately. It wouldn't even take a legion, it would take a mere few chapters. Hell maybe even just the Black Templars.
Tl;dr T'au are a waste in the story because they are not as numerous as orcs, they aren't as technologically advanced as necrons, and their warriors aren't nearly as effective as those from the imperium.
