How is that anti-trek? There's ALOT of firepower in those old cannons.
Wait, don't tell me... you're about to accuse me of bashing trek by comparing the Enterprise-D to an imperial star destroying and trying to figure out which one of them would win in a fight.
That's exactly what you sound like, one of
those crazies.
My typical answer to every similar argument is "Depends on who's writing the crossover episode."
Phasers dig a hole 1 mile long or help wipe out planets (Mirror, Mirror, Die is Cast, disrupters have similar power to phasers).
So do battleship guns. They just take a hell of a lot longer to do it.
As I said upthread, new weapons aren't necessarily more powerful than old ones, they typically do exactly what the old weapons do, only faster and more efficiently. Increases in relative hitting power DO happen, but not as a rule, and not neccesarily in conjunction with being more advanced (since WW-II battleship guns are still several times more powerful than any gun system now in use). You might, for example, consider the phaser effects from STXI, where Enterprise is able to fire all twelve of her phasers at a rate of about 300spm per emitter. If each phaser pulse has the kinetic energy of a 16-inch shell (about 500 megajoules per individual pulse) this means the Enterprise could lay waste to a city the size of New York in about fifteen minutes, Dresden Style. Even if phasers are less powerful than that (think 5-inch dp naval round) the effect is still that the ship delivers relatively small "bites" of firepower, just a hell of a lot OF them.
And this would still be consistent with what we see from individual phaser strikes against single targets, where phasers tear bus-sized holes in other starships even with their phasers down. Slight variations in these effects can be explained effectively by slight differences in material resilience and armor thickness (the torpedo bay on the Enterprise was probably one of the most heavily armored parts on the ship).
