It's interesting how the players with no respectable success in pvp are smacking the - (minus) on their comments.
To make things clear, the only time I had a problem facing Aegislash (to some extent) was when the opponent was skilled enough to use it properly (Swaglordx from above). It could be argued that for the same reason Greninja isn't considered to be broken in PRO, although it should've been banned a long time ago. I definitely don't want a new 'Gren' roaming in the fields of PRO pvp, as it's obviously unhealthy for the meta to thrive. That being said, a solid + for the ban of either king's shield or the entire mon from my side
