Feedback should probably be moved to gameplay to keep announcements clean. Just a suggestion.

Raiders (mounted combatats):

I've often thought this would make a great 5th orc adapt and even had some skill type thoughts for it. I'm going to put them here and you can use what you wish for Goblin Raiders.

Call Mount: Calls a mount. Dire wolf/War pig/Imagination. Might depend on terrain what you get. Mount initial level is Raider level x skill %.

Feed Mount: Used on PC corpse gives mount the veteran of battles effect, allowing it to grow beyond initial level. Carry's on over logout? Mount death resets.

Bonus to Ranged(ish) weapons: Obviously this fits with bow, but I was originally just envisioning spears and polearms. Allows you to make good use of pin. Chance for mount to cheap shot/trample. Bonus to charge/drive. Savage feed based on mount (bashing done with mount really, the rider can't get his mouth there.)

Mount Death: Big -morale (like bear), and crushing damage as mount falls on rider. Boneshatter-ish effect.

Ride: Ride in a direction quickly (shifter run-ish), potentially with some ability to combine with a target for a ride + charge combo. Lower mv cost. Inabilty to fly while mounted, but mounts are harder to trip/bash.

Attacks: Mounts do some basic attacks while riding (1 per round) and maybe 2 if you aren't riding them. Mount's can't rescue while riding, but targeting rider vs. mount is difficult and you will generally hit both sort of randomly.

Protection from environmental cold: Wolf keeps you warm. War pig?

Clan collaboration:

Bonuses for holding cabal items (give you a reason to action... you know, raid). Some thoughts on what those could be off the top of my head...

Fort: Resist light or remove light vuln.
Battle: 10 - 20% dam redux?
Scion: +200 hp
Empire: Disciple (orc guards behave more like Centurions, blocking people from entering clan village)
Tribunal: Extortion: Mafia payoff money going to logged in orcs.
Nexus: Some of the vanguard protect against big damage goodness or prot vs. good or something?

Other reasons to join Clan vs. join cabal... Not coming up with much here.

Specifically goblin skills:

SmellPrey: Some ability to sniff out PCs nearby. Think where from the skys, but with a return that lists maybe PC race and number of them nearby instead of actual names. Orcs don't care what elf it is nearby, just that there is one.

Bow cheat shot: Shooting an enemy that's been tripped or bashed seems to fit in with orc skills nicely. Probably not added lag, but purely damage like pin, but from a goblin that isn't tanking.

Distract/Circle (but with a bow): Some ability to circle an enemy (on your mount) and sending distracting bow shots to keep them from attack with as much efficiency as usual against their target. Something feint-ish or damage-ish. Like existing circle options + maybe something specifically to counteract swing or whatever it is called when an NPC/PC (AP) attacks all that are fighting it.

Set Snares: Ability to use the good versions of orc set snare and set them in wider variety of terrain. Lower timer on setting them/resetting them?

War Drums: Something to inspire goblin and orc alike. Personally I'd rather see a half-orc class of warsingers that are bard-ish, but I'm throwing it out there for you to do with what you wish.

All I got for the moment. I'm sure there are more ideas bouncing around the skull that will find their way to the surface again as this news reaches into the cobwebby corners of my mind over the next few days.
