Doubling up on Spectres

Currently you can give yourself your spectres twice without using extra spirit by using two different weapon sets with different gem requirements. You can easily do this by have one set that can use a gem at 55 strength and have the other set not meet the requirements (like one using gear to boost the stat) while having your spectre use a strength gem, then you use the first set and then swap to the second set and then remove the now inactive strength gem from the spectre. This results in your spectre buff being reapplied but the one from the other set still being active as well.
This is extremely easy to do and takes no longer then a few seconds. I've also had this happen once while swapping between two spectre sets while one of them was on cooldown to respawn but I haven't had it happen more then that one time.
