Please, make sandreavers tameable! Although there are so many other creatures that could become tameable, not to mention could be created in the first place (like frogs or sloths) sandreavers are a simple addition to the silithid family.

Li'l Sarinexx says "Tameable pweez!

There are only three sandreaver NPCs in the game, and these are Sarinexx, Kurinnaxx, and Fankriss the Unyielding. Sarinexx is a boss for a group arena quest, and the other two are raid bosses. This clearly shows that the entire sandreaver family, small as it may be, is utterly badass. And honestly, if we can tame silkworms, there is no excuse for being unable to tame their spikier desert-dwelling centipede cousins.
Although there are only three sandreaver NPCs in the game, there are six different skins.
Three of the skins, the ones used in game, have an interesting pattern along their back, and there are three others that are plain, and lack this pattern.

There's also a pink version that has no patterned variation.

Here are a few of the skins that Wain, the creative creature-colorer, has made:
A bright green/dark red combo, I could see these living in the hives in Un'Goro.
A striking white/black combo.
A deep blue skin, this would be cool for an underwater species.
Another sandy-type.
And finally, a bright poisonous-looking red.

So, you may ask, why is it so easy to make these tameable, as opposed to Hydras or Wyverns? Why, by adding them into the Silithid family, of course! By simply flipping the "tameable" switch and sticking them in the Silithid family, no new efforts to balance, add abilities, and specials are needed. If, for whatever reason, they are not put into the Silithid family, one of their special abilities could be

Sand Strike [Exotic Ability] - The sandreaver spits up sand in the enemy's eyes, blinding them for 4 sec, preventing healing for 3 sec, and slowing movement speed by 50% for 5 seconds.
Perhaps they could keep this ability even in the silithid family, although it would be a first to have separate types of abilities within the same family...
Just dreaming here: A rare or two could be added in Tanaris with the unused skins. Maybe they'd be "challenge tames", no matter the level: they could burrow underground frequently, which would interrupt taming, be immune to ice traps, and have to be rooted with the help of a friend.
So, please support the cause of tameable sandreavers! I'll make a similar topic on the Battle.net forums (the others were a year or so old, and definitely not close to MoP's release.)
Edit: I found out that when beast lored, the sandreavers have a diet. These were apparently added at the same time the Silithid Colossi (Boss Silithid) got theirs! Perhaps for some minor reason, the reavers never quite made it into the 4.0.1 update of those old raid bosses being tameable.
This is another good possibility for Mists of Pandaria- Blizzard fixing a "bug"
