It hits everyone else on the field, including teammates. How is it that not a drawback? Doubles is the official format for Pokemon now and I can't see that changing. With that in mind it's pretty certain that metagame balancing will be more focused on team battles.
I think earthquakes fine but some more SP attack moves would be nice
I think Earthquake is fine the way it is. I also think it makes sense for so many Pokemon to be able to use it, almost like a right of passage for final evolutions of sorts. I do think there needs to be a Special attack of same power and accuracy that is as widely available as Earthquake. Earth Power easily could've been that if it had 10 more accuracy and were more widely available.
I love using special attackers but man do we get the shaft sometimes.
earth power has 90 power and 100 accuracy. Its also somewhat better than EQ coz it has a chance to decrease special defense. The availability is the thing that's lacking.
