when i use politoed me sure lose one Pokemon when Gothitelle is sent into battle on a pokemon it can set up on.
when i use some pokemon tank like blissey/ferrossed Gothitelle to set up Calm Minds on each Pokemon is very long which makes battles dull and time-consuming. (i experience the most waste time is 30minit on my ferrossed)
it is difficult to know whether your opponent has a Gothitelle so you are not given a chance to play around it.
Even though Gothitelle can easily be revenge-killed, it can easily switch out to a counter. Especially with the lack of Pursuit.
