A lot of years ago they were included in a fishing event it would be nice if that sort of stuff happened a little more often

Just increase max price and k.

Increase max price for dream horses. I know that many are just sitting in stables all day long for selling is barely worth it. But they want each and every player cow to p2w for this. 

Now farming should be the activity to obtain those mats but that is so mindnumbingly boring and unrewarding, that only the most obsessed meticulous person would play it in the long run (or maybe those with really low gaming standards).

Yes, please.

Especially the Raibow Gem Fruit, since the only way to obtain it in game now is from the daily quest where you can choose with mat, or from the Peridot Petals (which also allow a choice.)

Since they removed Imperial Trading, there is no other way of obtaining them.

My suggestions would be:

1. Add it as an exchange option for the trading Silk

2. Make Peridot LEAVES exchangable for all 3 types of mats, not just the Hoof Roots. So exchange for Fruit, Conch or Hoof Root as you wish. 

That would equalize the ways of obtaning the three types of mats a lot more.

You can get Gem Fruit via hunting and farming. Rawr Rawr gives heaps too. But agreed, it'd be good if the leaves could be used to exchange any t9 mat.

I wish!

That's Furious Pouch of Feroucious Beast, which is a unicorn mat.  The Rainbow Gem Fruit is a pegasus mat.

I hunt and fish, which are the sources of the unicorn mats, so I have enough of those.
