Maybe they'll release an advanced class called "Summonest".

Alternatively,

"Summon 'er? I hardly had time to prepare the proper aetheric markings and begin the ritual to open a gate between realms!"

or,

"Summon 'er? Let me swiftcast first."

My biggest complaint about summoner is that y'all have made very few jokes on the name, or the fact that we're always horny :<
