It's very enjoyable, but the fact that a person who joins it may have to deal with up to 30 minutes of x1 and may not even get a multi at all if he keeps getting autobalanced to the attacking side means that much of the population will not play it most of the time simply due to a lack of incentive to do so compared to Battle. Fortunately, there is a way to fix this beyond just overhauling the maps or the mechanics of the mode itself--by rewarding Conquest participants based on their personal performance rather than their team's performance.
What I mean by this is, for Conquest and Conquest alone, the multiplier system being de-emphasized in favor of a modified reward system that is more in line with the goal-oriented nature of the mode. The way I would specifically implement it is as follows:
1.) You get xp and gold for kills. Killing people who are higher level and/or in more expensive equipment gives you more than killing a peasant in a linen tunic. Having a higher multiplier would not affect the xp and gold gained per kill.
2. You get a large amount of xp and gold for capturing a point. If multiple people capture it, the bonus is split equally between them. Having a higher multiplier would not affect the bonus awarded for capturing a point.
3.) The multiplier is still in place and increases on winning as it normally does, but the xp and gold rewarded by per tick is reduced to a fifth (this figure can be tweaked if it is too low or too high) of what you would usually get.
4.) Valor is still in place, meaning that getting a lot of good assists over the course of the round will not go unrewarded.
5.) Your total payout from kills and point captures is listed at the end of each round ala DTV.
6.) Upkeep is still in place and is handled as it usually is.
If they are not too difficult to code, these changes will encourage the community to play and populate the mode. Facing 30 minutes of x1 on joining or struggling to get a multiplier as an attacker is no longer a problem when you are getting the majority of your xp and gold from killing the enemy team/capturing the points under their control. More importantly, these changes will make it so that people can actually have fun and enjoy the best parts of the mode--lots of opportunities for group fighting and good pushes--without penalizing them (as the current system does) or rewarding them for doing things that are pointless or counterproductive.
