Yeah I said the same thing. In my experience I'd have to say unless you're sure you can get your koptas in without them breaking/being shot to pieces I'd just give em TL Rokkit Launchas. This is much more effective for tank hunting. If you're looking to make them anti-troop for anything with a good save the rokkits are pretty good still. Weak armor just keep the TL Heavy Shootas and give 'em Big Bombs.dang...
