what can be done to improve the phys ranged situation?

[grinkdaboy]

2 raid tiers now i have been unable to find a phys ranged player or anybody that wanted to play phys ranged and i have had a double caster comp. i could see that there were a few points (specifically p3s and p4s p1) that lacking the 1% bonus hobbled us, but more gear helped us push through it. i'm a melee main and have no interest in playing it, so, what could be done to make playing phys ranged not blow chunks? (and i'm not referring to encounter design giving more uptime and having humongous hitboxes which hey i welcome and maybe they should increase phys ranged numbers)
