How about we get these?



^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
WHY They only get those???

I can't remember the exact reason, if you do some digging in the archived suggestion forums, you'll find it. They did give a reason as to why we can't have multiple arms. We could as a possible back piece, but they would be stationary and unusable in combat (like the arachnid legs).

Not sure why we can't have psionic arms that mimic the regular arm movement.

It would he fine too they dont have to move i just want them to be there or...! Make use the same animation non-stop just like he tails!

An extra pair of arms would make a great addition to costumes and they might as well be included since there are parts for grondlings. In fact the only thing missing to make a believable grondling is the extra arms so not? They could be given extra skins so they could be psionic, robotic, or fleshy.

Extra arms, whole new skeletons, whole new set of animations.
That's why Grond, grondlings and extra armed PSIs use same set of powers/animations. You know, the SMASHes and THROW ROCKs.
