I dont know how many times it's been explained, but more popular ninjas = will beseen more. you know why we havent had the art for a new 3 sound genin? when at this point in the story do you see them?
"But what about X character! they dont show up and theres Y amount of them!"
Guess what? Kakashi,Asuma, hidan, hell even Hiruko, all more popular.
when all else fails, it just comes down to give the effect to someone. Jiobo has those meh effects, but ask yourself, would you REALLY run either of those effects OFF a jirobo? If say a haku, or other sound 4, or whatever water ninja did, would you really make roo? Probably not.
the fungal power thing was just dumb. Tylar said it best, andyes you pointed it out, wind is not the "pump" element so it's pumps are meh. guess what? blue in Magic is not a direct damage type element, but there are blue mana costing cards that inflict it. they just aren't as good as say anything in the Red section.
TL;DR - your "rant" was more pointless than.....well ranting. It said things already mentioned like a parrot to it's owner, and thats all. 1/10.
