So I was casually leveling my Lancer to 14 for Invigorate to help boost TP gain on my Archer. I was lost in grinding and noticed that when I hit with Trammel I was getting on average LESS OR EQUAL SP per hit than just using Heavy Thrust (LNC TP generation ability).
I had some Screenshots but didn't realize the game didn't have a Screenie folder so I was only able to save one via MS Paint, I'll have to get more later.
I got into testing this I was fighting Puk Hatchlings east of Skull Valley and Heavy Thrust was hitting for around 90 a pop and was giving roughly 55 to 65 SP per proc (not including the extra 20ish the Bind would sometimes proc).
Trammel was hitting anywhere from 200-240 and was ranging from 53 to 76 SP per proc, yes sometimes it gave more than Heavy Thrust could give, BUT, Trammel is doing DOUBLE the damage so I could Heavy Thrust twice for 180 and possibly get 110-130 SP.
I also decided to equip Doomspike just to test some more. This was harder to test since it was harder to use in general and the damage changes since it just drains your remaining TP after 2k is achieved. But it was averaging about 400 damage and only procing around 50 SP. I remember one very sad moment though.
Doomspike hit for 464 and proc'd 44 SKILL POINTS! which is crazy and just not right. These hits were all on Puk Hatchlings which yes could range a few ranks but still a 464 hit should not be giving 44 skill points when my normal Heavy Thrust hits were giving no less than 55 regardless of what Puk I was fighting.
Needless to say I switched to just spamming Heavy Thrust and ignoring my TP abilities and was gaining a lot more SP per fight because of it. I went from barely breaking 100 every fight to easily breaking 300.
