can someone explain why the ratios on these are so far off

warrior we have 5 4 sets
magus we have 6 4 sets
gunner we have 6 4 sets
sentinel we have 2 4 sets
assasin we have 3 4 sets

ok so here is my issue the quake 4 set is shit so the only decent thing green has is greed which sucks when others have so much more

assasin has
shadow
fallen
and reaper

all 3 are decent enough so can we get some love for the sent sets
