Actually, we used minis and grids more in 2E than in 3E. Since the advent of 3E, we've upgraded our minis, terrain and all that to the point where we have so much nice terrain that we only use that for major battles - minor battles are just resolved with dice and descriptions. In 2E, we just had a regular battlemat and minis that we kept out all night.
But now, we have Mage-Knight castles, lots of terrain, etc. So, we only drag that out for special occasions, as it takes a bit to set up and all. And, I have some special minis that I've had painted up by top professional painters that I prefer not to use except for those special "climactic battle" situations.
