after some thought ive decided i'd swap warlords for reavers, this way i still have my battlegroup of 3 titans. the difference is i decided to arm them the same.
with the left over points i think i'd try 2 formations of forge knights, they look promising being able to charge and break formations before they act, also can use them to beat up tough units like RA tanks and titans.i can also use the veteran princeps to declare a commander charge with the 2 formations on something really tough like an enemy warlord to down it outright.
these 2 formations should make up for the lack of sheer power the warlords brang but give me tough units i can clear out objectives with and then hold them while the titans pound away advancing towards a set objective.
heres the list mark 2

Reaver Titan - 575
Veteran Princeps - 25
Carapace Multi-Lasers - 25
Carapace Mounted Quake Cannon - 75
Arm Mounted Gatling Cannon - 25
Arm Mounted Plasma Cannon - 25 = 750
Reaver Titan - 575
Carapace Multi-Lasers - 25
Carapace Mounted Quake Cannon - 75
Arm Mounted Gatling Cannon - 25
Arm Mounted Plasma Cannon - 25 = 725
Reaver Titan - 575
Carapace Multi-Lasers - 25
Carapace Mounted Quake Cannon - 75
Arm Mounted Gatling Cannon - 25
Arm Mounted Plasma Cannon - 25 = 725
6 Forge Knights - 400 = 400
6 Forge Knights - 400 = 400
Total = 3000
ps. i like the missile launchers on the GW reaver model so will be using them as "quake missile launchers"
how do you think this would do now?
