everyone for some reason is always afraid of stab eq's coming from more than base 100 atk.
May I remind you that unboosted doryuuzu is not dangerous, and that boosted rock slides aren't that bad. Seriously, zuruzukin can switch in with impunity on the obvious swords dance. (and it really really is obvious.), then take a hit, use drain punch to regain enough health to most likely take another. Shibirudon is a similar case. Unboosted or un stabbed hits shouldn't cause so much panic. ie ramparados has trouble bludgeoning uu walls. When you have thin defenses, even with a speed boosting ability, you're powerful but not broken. For example, Garchomp, who truly may be broken, is so because he has more defenses than swampert, great offensive typing, and a good speed number. Doryuuzu has higher attack and speed, but that doesn't mean it's better than garchomp, for the aforementioned reasons. It doesn't help that weather changers can revenge him. (with choice items.)
