Just can't kill this thing with frigates unless you steal all its antimatter . Then its just a sitting duck.
Which is why I really wish every faction had an effective means of depleting titan antimatter. As it stands Vasari have a great tool for doing so(kortul), TEC have a less-then-ideal tool(EMP has a pretty long cooldown since it's AoE), and Advent doesn't have squat since not even the damage/antimatter aspect of Detonate Antimatter can be used on titans. Then again, in general I think the idea of depleting the AM of a titan so it can't do it's thing feels a bit lame to me in general(not much different from the CC effects titans are immune to)-but it strikes me as a bit of an issue that some factions are substantially more adept then others at shutting down titans in this fashion.
Then again the TLT is a special case I suppose, honestly I'm of the opinion that putting such a strong AoE damage ability(mostly due to the insane area it covers) on a titan who's main selling point is it's borderline invincibility(3 defensive skills and high base hull/shields) may have been a less then wise idea.
