I think the suggestion made for LABs could work here too. Loyalists are fine as they are, a good counterpoint to the Brick, but Titans?
The suggestion was that the point of raiding units is to raid. That is, to attack mexes, pgens, engies. Things, in short, which
can't fight back. The reason LABs are underused for this purpose is because they can't do combat well, but they also don't kill things very fast. So we lower HP and raise DPS, keeping all other things the same, such that their combat balance against T1 tanks is unchanged, but their ability to raid their intended targets is enhanced.
This same logic applies perfectly to the Titan IMO. No, it should not ever be able to wage war against T3 units, or even be successful against T2 combat units. It also shouldn't be made a Loyalist clone in design or ability. It should be unique. Lower the HP, raise the DPS, leave everything else the same, and we end up with a unit which is fast enough to get behind lines, as now, but now instead of having all the time in the world to get your ACU to the back of your base to deal with them before they do serious damage, that T3 PGen is smoky bacon and your HQ is toasty fried.
At risk of damaging the legitimacy of the above argument, here's a semi-joke suggestion: We could also allow Titans to fire from transports. T3 Ghetto Gunship just became a REAL thing
