What do you normally do with your Acclamators once you reach Tech 2 and have access to VSD's?

I normally put 5-6 with my main land force as an escort, and use the remaining ships to defend unimportant or rarely attacked planets.

Surpluss Acclamators will be used as cannon fodder in my main fleet, softening the enemy before my primary assault.

Yeah I do pretty much the same thing as you :p I still like to keep a few in my main fleet. Since their pop cost is lower then a VSD, you get access to more free fighters (until I can get a better ISD and VSD combo). Usually though, I keep them on planets that need little defense so they can put up some decent resistance against invaders.

I find that Acclamators are still useful in later stages, particularly since they have proton torpedo (and concussion missile) launchers. Always nice for targetting the Rebel ships' shield generators...

Uhm - it's not? Both the VSD's and the Acclamator's pop in space is 3 - which is also why they truly are pretty useless once you reach lvl 2 - I use the to defend unimportant planets or to blockade rebel planets beofre blowing them up with the DS :D

Really? I always had access to more Acclamators when using them in a combo with an ISD as opposed to the VSD. Perhaps I forgot another variable...
