this reverts rP26474 in favor of keeping them strong against buildings but less strong against units.
this also:
reduced the accuracy of the fire cav from 1.6 to 4 (the value of normal javelineers) -> this should help nerf them vs units but keep their strengths vs buildings
lowers their pierce damage from 35 to 25 (just to round up the package)
I've run some tests vs the briton chariot champ and feel like their equally strong now (so the fire cav is still better as is has the added bonus vs buildings)
all based on the discussion here: https://wildfiregames.com/forum/topic/72452-tasklist-for-closing-out-a26/
