Since this is sort of becoming a "We want EW back just because" thread, I suppose i'll post as well.
Castle wars currently offers next to no good rewards that will give you straight up cash, this is why most lower levels don't play it which is all pretty logical. The minigame requires 10 people to start, this often causes problems because not everyone has 10 friends willing to do CW. However if you need exp for skills brawlers are one of the best things to get, not only do they make things faster, they can also save you money because you'll use less of your skilling materials. Rewards like nezzy and ava aren't worth getting because of their low price. CW rewards don't give you direct cash, they do save you time/money when skilling if you get brawlers.
Onto the subject of EW, I honestly don't think there's any other reason than nostalgia that people want it back. I remember playing the minigame as someone that had just gotten a whip and bandos, the rewards weren't worth it back then, even with ss and void in the shop. You couldn't even affect the amount of tickets you got if you were a lower level, it was 1 for losing, 2 for winning, the +5 for most damage was far out of reach. While EW definitely was about as much fun as CW, CW makes more sense as a minigame. CW isn't a matter of which team has more killing power, it's a matter of which team gets the most flags, which isn't as gear related as killing the enemy boss was.
CW really just needs some new good rewards, cosmetics don't cut it. Something like dxp scrolls or just flat out exp like in pest control could definitely blow some more life into CW. Though really, our playercount still isn't high enough to keep minigames running all day, and everyone keeps forgetting this.
