Field Repair Bot--Follow

If anything, I would expect a new repair bot.

For clarity, when I refer to a repair bot, I'm refering to the stack of five you get when you do one combine of the schematic.

The bots take, among other things, one Khorium Power Core to make. There are three options to get a Khorium Power Core:

1) Luck out and find one at an engineering supplies vendor.
2) Mine 6 Khorium Ore (could take up to 3 nodes to get those ore) and farm a Primal Fire.
3) Buy the materials on auction (at a current cost of well over 100g on my realm since they're so rare to find now that Outland is deserted except for an army of DKs and a tiny handful of alts and new players).

In other words, a costly item to make pre-Wrath is even more costly now, whether you buy the mats or invest the time to go out and try to get them for "free" (or cheap, in terms of the core from the vendor, who only sells 1 every 24 hours or so).

So now you've spent potentially hours accumulating mats for one bot, or you've spent so much on mats for it that each bot you drop costs you upwards of 20g.

If you consider the scenarios where a person might use a bot, it becomes even less worthwhile in all but the most extreme situations.

1) Solo. I don't know about you, but I've never let my gear get so run down solo that paying the heinous repair bot prices to repair + cost of bot is better than a quick trip to town.
2) 5-mans. Maybe as a convenience in a heroic group if you're struggling, but you'd have to be struggling pretty badly to break your gear if everyone showed up fully repaired. If they didn't show up fully repaired, they need a smack anyways. I'm not going to waste a bot on someone whose gear breaks after 2 wipes because they're irresponsible.
3) Raids. Same deal...you have to be pushing hard at progression to need a repair midway through. If a bot is going to be used anywhere, it's likely to be used in a raid where the guild bank will fund the mats. Most established raiding guilds, however, are using a mammoth outside the dungeon for repairs after repeated wipes. If your guild doesn't have officers with mammoths, a bot is still a reasonable alternative.

As far as consumables from a bot...people pay ridiculous bot prices for consumables because they weren't fully stocked when they showed up. My hunter never went to a dungeon or raid without a full quiver/ammo pouch, and I never once ran out of ammunition, even through 4 hour progression slogs and it wasn't because I was holding back. If you run out because you forgot, oops. Doesn't make you a horrible person, but dropping a 20g+ bot to stock up again is a pretty poor solution.

Hence, if there is to be in-instance consumables to be had, it will most likely come from a new bot introduced at some point in a future patch.
