No...
...correction: DEFINITELY NO!!
Certain units like for example Commandos are supposed to use their stealth to get in close without getting picked off and also effectively counter MGs.
Oke, but why can they stay in cloak whilst covering so much distance? It is brain dead and unfair. They have insane dps and a mini satchell nuke nade that has a second timer. This unit has too much.
The problem with cloaked Rakettens is once they reach vet 1, it is almost impossible to catch them unless you bump into them by accident. Have two of them at vet 1 cloaked running around the field and no armor is safe, unless they hit the ground
