2vs2 with a ranged and a melee in each team ? Will never happen :*(
And anyway, Robinhood and Tutti would win it
I think the shielder and throwing lance team would win rather easily tbh. With only one ranged guy, you can negate the opposing team's single ranged character rather easily, until you get close enough to start lobbing lances. Have the shielder turtle/distract the the other team's melee once he's close enough for the thrower to start fighting the archer, then 2v1 the other melee/chuck the rest of the lances.
You know how you can tell if a weapon is OP? If in a competitive setting, exceptions would have to be made to make sure it was banned.
