I had/have doubts about the outrider's weapon myself. However,
that spear was what wciow gave it to start off and to be changed, well, here are my thoughts about it:
1. Another spear? Hadn't really thought of it. Still, that will be, to me the most peaceful of all changes...
Why? See next point:
2. A weapon other than a spear will (almost) definitely mean a range 1 mellee attack instead of the current range 3 "mellee" (I read somewhere attacks up to range 3 are still considered "mellee"). Now that range change would have an important impact on the unit's balance. We
could boost up the attack damage to compensate for the loss of range; however, cuttting range on an unit that is greater than size 1 also has other impacts (a size 2 unit may not manoeuver around as easily to get to the enemy as a size 1).
3. That being said, giving the outrider a weapon other than a ranged one (a spear, a long chain with a spiked ball on the end, possibly a bow or a sling) is tricky and in this particular case I think utterly silly! See why bellow:
4. The outrider carrying a battleaxe (though it would
apparently look awesome would simply NOT work ingame! Why? Simply because the rider can not use it along the side of the rhinox (that's what you were thinking of, hey wyvern?). In Glest, the attack is ALWAYS struck to the front of the unit (NEVER to the sides, back, or whatever). Can you imagine the rider leaning almost impossibly forward to strike a blow with his axe AHEAD of the rhinox's head?
5. The rhinox has THREE HUGE HORNS on its head (and they got to be and can get to be even bigger again)!!!! WTH would you want to give it any other weapon for a range 1 attack?!?!?!?!?!?!?!?
THAT is the Outrider's perfect range 1 weapon!
So... what's your take on it, Arch?
If you just want to give it another range 3 spear, yeah, go ahead, why not?
EDIT: On "other weapons changes" (for other units?), post your thoughts!
