It turned somewhat worse for the turtling engie, but the offensive engie is still fun to play. Just never build more than a level 1 sentry on the biggest hotspots and lure people in it, while attacking them with your shotgun at the same time. Works wonders. On another note, I remember the word 'stacking' only to be used when one team actually had more players than the other. Now it's just friends who join one team, and thus have an advantage in teamwork, nothing more. But that's the whole point of the game, the team with the most teamwork wins.
