Well i don't really know by what you mean how i'd like to spar but
I like to have an assortment of large ranged weapons, not all of them have to be just mega powerful i prefer a variety like a multi elemental weapon for example
and for close quarters swords and daggers chains and some mid range weapons like hand guns. Speed is an absolute neccesity and atleast a semi high level of evasiveness coupled with charge-in attacks. Another thing i'd really like would be a Gravitron, that would let me cntrol object's around me let's say rerieve a nearby item with in a certain distance of my mech or use bits of debris as improvised mid to long range projectile weapons.
