Loved 'em from the first starter of MK I opened! The Blade Golem was prominent in the included comic as the premier 'bad guy'.
Currently I play them in single faction armies. To increase their effectiveness in melee, I'd love to see mounteds have less chance of breakaway from 'em though...
Haven't tried them in conquest, too busy with orcs, et. al. But I should, considering all the raves on this thread!

run gun can stop the big bounder ... i'll prolly have to build one myself just to stop a GUY who loves using this bounder :) lol ... hehehe

When I first started playing, I didn't appreciate Blade Golems at all. (I think I got my butt kicked while playing them and banished them to the back of the box). But now I have seen the light. :p I use them to run over the enemy and to shield my magic blasters. They're also fun to paint if you like metallics.
