Every company is driven by the inflow of revenue and reports to shareholders. Look at games produced by Blizzard entertainment for example, and a card game like hearthstone in which I managed to reach legend level, have the card back to prove it. I can tell you there is no balance in it at all!!
This game to an extent tries to balance things out, the idea of expanding maps and make it that players can multipath giving them more options to out maneuver opponents, like blocking the view of those who have reached a spot close to their spawn and are trying to snipe someone reaching the point of capture should be looked into. Definitely if there is one issue that needs attention is the creation of new maps for top tier 9.0br and above. Maps like Vietnam for example do a good job of not allowing some one to stay in one spot and control large portions of the map. It is not a huge map but players can maneuver and out smart opponents.
It is different to a city map in which only few paths are available to impact the objectives of the game so everyone flocks to them. Vietnam style maps will also prevent people from snipping and controlling an entire area. I think gajiin should focus on creating such maps. Their newer map with the ancient ruins is an ok example of this but there are too many elevated positions from which individuals can impact point capture. Otherwise the rest of the maps offers many oppositions to players who can out-smart opponents. Gajiin should focus on creating maps like that.
They wont take super long to finish but will give players the ability to maneuver around the map by reaching spots from which they cant be easily seen by those that are snipping and looking for easy kills.
