To add a bit on the telekinesis thing:

To me it looked like Erza was just flinging the weapons around in the general direction of the enemies and the only reason they connected was that there were so many. On this page in the upper left frame we see at least two weapons flying around in an area without any enemies.

Using an ability that can easily be used to land pinpoint attacks in a "spray and pray" fashion isn't what I would call mastery.
