Good point.

I think it's perfectly fine to not have Titans as an option, as Battle Titans quickly become the focal point of a typical 3000 pts game. Maybe allow a single pack of Warhounds?

On another point, one thing I think Epic lacks is a list that's built around a single Battle Titan. I think a 3000pts army could be one Battle Titan supported by a pack of Scout Titans and the rest infantry and armoured vehicles. But an army like that is legal under no existing army list.

Strictly speaking, a defensive list is exactly where you are most likely to find the AdMech deploying titans, especially if it's their forge world that's under attack. We have the fluff from Gryphonne IV speaking of the titans striding out to do battle with the nids and to a lesser extent, the game "Space Marine" has a warlord titan activated to do a surprisingly pathetic job at defending the FW. A route I'm trying in the current G draft is to reduce the allies to 25%. That all but eliminates the Warlord from any games 3k and under leaving you with warhounds and reavers which make for more interesting titan support.
