man im so glad to see people requesting "the pit" that is one of, if not THE best, competitive 4v4 multiplayer maps ever created. right now i think "the pit" would be closer to realistic function in H4 but unless they make the sprinting ability optional for customs it would only be good for slayer IMO.
i would love to see lockout and midship comback as well but with the sprint feature permanent those two maps would be a shotgun or AR fest unless expanded. also all of the competitve/MLG/4v4 maps from H2 and H3 seemed designed for the BR, obviously, so unless these maps were expanded somehow i see the death of the DMR.
Hang em' high would be a good DMR map i think but would need quite a few adjustments to the catwalks and ground level to avoid clustering on base tops. maybe a way to flank other than hugging the walls with no cover. maybe multiplying the exsisting map size by 1.5 or 2, and putting the bases slightly closer together... who know just this guys opinion
