Lancer is a TP machine. I rarely use anything other than Full Strike now (Heavy Strike on mobs you don't want to feed TP to like Chigoes and Pierce if I an soloing leves). If you engage (under Speed Surge) with FS you'll have 500+ TP in two hits, land Comrade in Arms and in about 6 or 7 hits you'll have 2000TP. Hit Moonrise > Skull Sunder > Heavy Trammel and if all three land the mob should be just about done for. If not, rinse and repeat.

The main frustration with LNC is your stamina can't keep up with your TP bar!
