Even with a dreadnought with fleet?
i field 5 of them so i don't spend to much, and its to really just get the dreadnought that really messes up infantry.
more than once my blood talons went against a terminator squad and the dreadnought took all or all but one out in 1 assault phase.
and they would be in a transport. to counter rage. and they almost always take out 50 more points of the opposing army than i spend on them...
