Honestly, I love all the new changes to pieces, but there are a few more things I'd like to ask for, but they're pretty easy. First off, I wish that there were wild, tameable versions of the storm and mist sabers, without armor of course. I just find it strange that there are so many of them used as mounts, but there arn't any in the wild. The same could be said of the dawn saber. Being that they are said to be only the strongest cats, I am perfectly fine with them being old world rares if that's the easiest way to put them in. I vote for them being rares in winterspring or Teldrassil, since those are the homelands of the saber cats.
Now then, on to winterspring. Specifically, frostsaber rock. I have a very strong attachment to that place in game, as I was always fascinated by the idea of haveing a war-cat as a companion. I remember my baby days on my first hunter, staring longingly at the sleeping sabers in Darnassus, dreaming of the day when I would ride one. And I was a dwarf, there was no reason for me to be in darnassus, other than to stare at those cats. And then I leveled. I spent so much time and effort farming rune cloth and doing the Nelf starting quests to get one of those beautiful cats, and when I was finally exalted, it was one of the happiest days I've had in wow. And then I set my sights on an even higher prize; the winterspring frostsaber. I had gotten all the way to honored before the first rep change, and I was just at the end of revered when the second happened. I have my saber.
Now then, that said, the whole reason for this, is that I'd like to see frostsaber rock revamped with some of the existing saber models, since it's supposed to be the home of the frostsabers. This is how I would go about doing it.
I would like the normal frostsabers to be changed to:
I would like to see the frost saber stalkers changed to the riding ice model.

.
I would like to see the frostsaber huntresses changed to:
I would like to see Sian'rotam return as a permanent fixture like his mate, and be changed to:
This would both give shy a proper mate again and provide a source of the white striped skin that isn't a rare spawn. It would also free up rak'shiri for other rare skins or her old minty skin, either way. I was thinking also that maybe the mint could be made the rare and shy changed into a storm saber instead of adding another rare, but either way, whatever is easiest for you.
That would leave the forstsaber cubs for people who like the smaller white skin, and the smaller white tiger skin is readily available on the non rare spawn King Bangalesh.
I would like to see an unarmored version of the storm saber and the mist saber as rare spawns
TL;DR version:
I would like to see frostsaber rock updated in the following ways:
Frostsabers = small ice skin
Frostsaber stalkers = riding ice skin
frostsaber huntresses = riding white skin
frostsaber cubs = stay same
frostsaber pridewatchers = stay same
Rak'shiri = mint skin/stormsaber skin
Shy'rotam = stormsaber with no armor or stay same
Sian'rotam - come back and be a permanent fixture like Shy'rotam = riding white striped skin
Personally, I'd like to see the ice skins the most, as the white tigers don't fit as well in the zone as the ice skin does to me. And they are available at a lower level.
