So when an ally leaves....replaced by henchman!!!

Its simple.

you're halfway through a grueling mission and your monk leaves. instead of being 97% skrewed, you're only 3% skrewed, cuz that monk that left has been replaced by a healing henchmen!

the henchmen that comes in directly relates to the primary proffesion of the leaving player.

Imo, something which should be introduced to PvP and PvE alike, (at the end of a battle in PvP).

Please read over some of the threads that already have your idea embedded within:
