... dump 60 points in TM and have infinite contraction due to PTA and FO...
I think you cant have infinite contraction without Stasis. And the actual effect of PtC + LTI are not powerful due to their high psi cost and PtC's reversing mechanism.
------
PtC has 3 turns duration and 5 turns cooldown with PtA and FO. FTI has 2 turns cooldown with FO.
Lets say you cast PtC at 1st turn, then you will lose contraction buff at the end of 3rd turn. If you always cast LTI whenever you can (at 1st, 3rd, 5th, 7th, 9th, ... turn), then you can cast PtC at 4th/7th turn, and lose contraction buff at the end of 6th/9th turn.
The problem is 10th turn, PtC still has 1 turn cooldown but you already lose contraction buff.
------
And the actual average AP/Turn in this 10 turns is not as high as 20 AP/Turn.
Every end of contraction buff will trigger a random roll (60% chance with 60 TM) that may gives yourself a PtD debuff, and its power (AP and MP) is slightly weaker than your PtA's power but has a longer duration.
Another problem is psi cost. 3 PtC and 5 LTI cost 3*50 + 5*35 = 325 psi points. So you need at least 3 psi boosters (100+75*3 = 325), and that means 30 AP.
Expect Average AP/Turn = (20*3*3 - 60%*20*(3*2+1) - 10*3) / 10 = (180-84-30) / 10 = 6.6
And this 6.6 AP/Turn cost 2 feats, 60 skill points, a lot of psi boosters and 2 psi slots.
