Glad to see everyone like discussing this in details, for information there's already a place who answered the basic question about it,

I think I know what you mean, and I'm almost certain she is right, a thruster CAN'T make you go faster than the speed at which the propellant is expelled.
If your fusion engine propel the reaction mass at 15% of the speed of light, then no matter how much reaction mass you have you'll never go above 15%
Other engines who look "weak" like ligth-sail can actually get close of light speed because they are propelled by photon or reaction mass that are expelled at far greater fraction of the speed of light.

The answer is somewhere on this website

It's also quite good to get rid of misconception.
Even if you know everything on that list there's certainly many more idea you never bothered to question but is actually very wrong.
