Duh, that is because it is my idea, I only come up with good ideas, I ignore the bad ones other than the one to leave the server<3
A lovely faction battle would be much better than siege.
It could be all arranged, a time and a place, our lovely team of admins! could make a place, a snow or land or villiage to fight in, purely to have battles, make things there that you could use while in battle, trenches, tunnels, or just open grass land, also people can have tactics archers/swordsman in places that help.
Also could imagine this, high up, mountains and a long thin bridge, two factions, either side, endless epic fun.
Or, a village, properly made, not some crap of wood or cobble piled, actually have a nice looking place, instead of "siege" could have "battle time", I say this because, I could imagine people be like but who would do battles? it is easier to just mindlessly pick on small factions and get greedy using siege battles like a bunch of Willzinos, I would reply to that with this idea, village war zone, with loot inside homes, so people actually have more than a goal of mindless killing, or of course, go and ruin some newbie faction's base and steal their cobble stacks and apples, I mean I am sure it will be worth completely wrecking someone's base and game play so they think they don't get a chance in hell to even grow on the server and leaving.
Also, you could have a battle but again other than just senseless killing, have a chest or a certain type of block that people need to collect and store in their faction's chest.
(Faction in a area, either side of each other with a chest where they are setting up for battle, this chest being the one they store the block or item that is needed, while the other team does the same, or at least tries, could have time limit, or have something like the first faction to get say...10 slime balls in their chest wins a prize.)
Again, instead of sieges, as instead of just being a copycat server and becoming a default PvP server, you could do events/battle times where you have a team starting on a ship at a beach, who have to go up this beach on to sand/grass and going like 40 blocks of that up to a castle where another faction is, this other faction would be defending a chest with for example a piece of fire that they have to take back to their ship and light a preset piece of netherrack to win the round then switch it around and have endless fun of games and events.
Another idea:3 would be to have two big ships in the middle of the deep ocean, where a faction has their own ship, the factions of course having to battle it out with each other, bows mainly but also swords if wanted, stick a ladder on the side of each ship and have it so people can board each others ship and duel each other, goal being last man standing.
Another idea being, having as many factions as possible, to be in a sort of arena area, with the goal being to get to the middle and stay there for a minute (Admins would need to be around of course:3), but the twist to this would be the fact getting to the middle would be extremely difficult as you could have slow sand in places, water, lava and fire to avoid, as well as mobs, zombie hordes around the middle, skeletons all around, so a very difficult event/battle, but again make it worth while, such as armour for all the member's of the winning faction, coins.
With all these ideas, I would add a wall of fame or "Hall of Champions" a place that looks very epic by itself, but also have shops in their that are cheaper and sell items that no other shop sells, the idea being, only "Champions" could shop their.
Also having like a sign with "Ship Battle" and under the factions that have won it.
To note, personally I think ideas like these are better in general for these reasons, it means team work, which means people working together, getting on together, less rage.
Also should mean that unlike a siege event where people will go for all they can get their greedy hands on, with these evens they all get a piece of the cake, but again with siege people won't group together to fight factions like RMM, but my ideas, logically people will need to work together, no cheat each other and to just join up and battle for the fame, glory and fortune that they could receive.
