Ok, so today I am Rank 24 Lancer and I got a Tortoiseshell Harpoon which is 5 ranks higher than my current rank. Well a good 11 size party decided to go fight some efts which I was gaining 500sp per kill. So I started to watch what was giving me my most SP per hit and this is what I noticed... My heavy thrust when proc'd on both the hit and debuff gave me ~250sp and my Comrade in Arms was giving me ~100 on proc.
Though my TP attacks which the three I use are Trammel, Moonstrike, and Leg Sweep were all not procing for any SP gain. All three attacks have the ability to give me attack SP and debuff SP gains, but no matter how many times I used them they never proc'd for any SP gain. We fought at least 20 efts, a few crabs, some orobons, and a few jellyfish and never did my TP attacks give me SP gains. I was using all three TP attacks once a fight with the efts if not twice. At least twice during crabs and maybe one or two during the orobons and jellyfish.
After noticing this I switched to my Brass Spear +1 which is 8 ranks below me. The first time I used Trammel I proc'd on both damage and debuff SP gain and after the weapon switch I started to gain here and there on TP moves some for damage and some for debuff and sometimes both.
Can anyone back me up on this? I don't want to throw out bad info, but it seemed pretty solid or I just had some really bad luck.
