Who knows, have to find out if its a problem first. It was definitively a problem with the old 125 point sieger companies. Other unit types can be spammed very effectively. A marines cant as they have no ranged fire and are pretty bad at assaults

Can these chaps? With FW/Crisis as the base you don't have much AT, so a good army to try against would be I reckon an Imperial Guard tank army. Two variants I can think of.
'Standard' high activation force
900  12 Drone Formations
350 SC crisis
1000 5 FW formations
600 6 Orca
150 Tigershark
25 activations
Out activate opponent then hit with firewarriors and Orca (AT).
or manta force
850 Manta
900  12 Drone Formations
250 Crisis
1000 5 FW formations
19 activations
Out activation then hit with manta free from any counterstrike turn 1, and maybe go first turn 2

Any fixes would wait on is it a winning combo, then if it is and you don't want armies like that you can look at the options.
