If you try to build a wall under the CV (only tried NF CV) you can push him along as an engineer really quite quickly, quite an effective trick to get the enemy commander into water very quickly.
placing turrets under cv is way more efficient, and old trick is old trick, and you wont do that if the coms not dumb
2bh, its genius, no "the commander is under attack" You can just push him along into the water, easily done on some maps, i can see it working on slaughtered, and it did work on temple.
Dude, that's a genius way to ninja. But unfortunately it'll on maps with water (of course) and situations where their comm is parked beside a lake (slaughtered)
