OH HELL YES I LOVE TERRORBLADE'S IMAGES!
by the time you reach middle game, terrorblade's image's armor and
damage output is decent enough to pass for the real thing, and very
often the image's are able to tank towers.
often my image helps me get the kill too, especially when i'm taken
out of combat (eg: nightmare, cyclone). there was one game i could
never forget though. my image managed to get a double kill after i
died in a 2v1 gangbang, and on another 3 occasions in the same game
my image got the kill again for me when my hero was taken out of
action.
also if your able to control your images well enough, often they
tend to cast spells on your image instead of you. actually lately,
i find that my images are the ones being hit by the spells 80% of
the time. in fact usually i get them to attack a disabler from the
front, get them to spam whatever disable spells they have on my
image, then i come and whack them from the back. 
once i was pushing the top lane, but i didn't want to win so fast
so i backed off, and left an image in my place. guessed i controled
the image well enough that the CM on the enemy's team bit (frost)
me and starting casting freezing field. hehe. 
another incident was just after pushing down both barracks on the
top lane, and i decided to run before i got ganged. anyway i
decided to leave an image there, and i guess the veno on their team
saw that it was an image, so he just let it hit him. however after
about 10 seconds, his hp dropped to 1/5 and thought that my image
was really me, and started to run. my image continued to chase him,
and all i needed was just one more hit to kill him. he ran to the
fountain, so my image got killed by a firebush, but the whole thing
was kind of ammusing. i mean your running for your life and you
find out that the person chasing you is an image.
