The Advent titans do have at least as many strikecraft as a carrier capitalship, though I'm not sure about starting with 7.
That said, one of the reasons they may have tried to avoid a carrier titan is 1. Strikecraft are one of the major causes of lag. Making a titan rely on using tons of them when they have other options was probably wise. 2. If you have a ship have a lot of buffs and strikecraft it can get too big for the infocards, and as titans tend to get affected by lots of abilities that would probably happen a lot.
That said, I'm sure I'll be messing around with a strikecraft themed titan sooner or later...
