Well I was playing Medival 2 total war with Russia got in a war with Hungary destroyed Hungary then went to war with poland asked for a cease fire after around 100 turns of war then venice attacked me and i got pissed and made 1000 assassins(i am VERY VERY rich)which was cool i was laughting my ass off when the guy failed especialy wene the door hits him and he stabs himself bt exident i rofled that time.So for the ideas i got ideas
(1)Assassin Class:Maby a class or skill so that you can make assassins and a little film or minigame wene you are assassinating or sabotashing
(2)Guilds:The guilds in medival 2 total war are cool also help like the assassins guild helps make better assassins then the master assassins guild then the assassins HQ all made the assassins better at well assassinating would be cool to have guilds in ElementaL lilke Sword Forge Guild for making better swords and stuff.
(3)Assassin Faction:Well...While I was playing with my army of assassins i thought it would be cool to have a faction of assassins.Did you ever play Assassin's Creed?well they were a faction of Assassins in AC2 it was even cooler having your own city and stuff.So If you had an Assassin Faction in ElementaL like having assassins skills good at stealth and taking out targets yet bad at mass battles because they are well assassins not soliders i would love for my SOV to have a hood would look COOL!
(4)Stats:The "Generals" in Medival 2 Total War had stats like "Command" "Dread" ect also had Ancillarys and traits like "Master Attacker" which made him good at attacking and in ancillary had "Fine Armor" which increased his HP.it was cool im sure ElementaL can have things like i dont know "Respected Leader" + Respect from Population and other factions.
(5)Equipment:Well I would love it to be just for looks i dont mind if its for looks and you pick how much protection it gives so there will be something like STATS but seperated for Equipment like in RPG's there is "Intelligence" "Cunning" "Strength" "Constitution(Prostitution if you ask me)" well we could have stats for armor like "Defense" "Reflex" "Magic(for things easyer use of magic or somethin)" and for weapons "Speed" "Strenght" "Cut(Makes easyer to cut throught armor likr blunt wepons should have 0 cut)"...this would solve 2 problems 1)People will Actualy pick what they want to look like so they will look cool 2)People wont all pick the best equipment and we wont have like 300 people with the same equipment running around beating the f**k out of people who chose to look nice but s***y stats for equipment...and obviusly if u dont have armor you dont get stats.
(6)Religion:Well in Medival 2 Total War and Civilization 3 there is religion and it dose have an effect on the game like Religius unrest that may cause riots and wars between contrys(just like real life if you ask me) so it would be nice to have religion in ElementaL could even have some lore to it.Would be nice to be able to create your own religion as well more lore for ElementaL if you ask me.In Medival 2 Total War they had a "Religion" under the name of "heresy" a "heretic" spread that religion I usualy assassinated him since i had a spare 1000 assassins anyways.
(7)A Rebel Faction:A Faction that is with no one and is against everyone should be organized and maby has a city or two which are "ruins of a city turned into a place to live" still this is not much of a idea but a good way to get exp "run around killin rebels wait for more repeat"
(8)Customizable Equipment:Customizable to a point you can actually make a item and equipt on the SOV
(9)Customizable Religion:This is partly in point 6 but making a religion choosing its symbol and writing some lore about it would be a nice asset into the game and a good way to spent time if you have nothing better to do 
(10)After Battle Choices:In Medival 2 Total War wene you won a battle you had 3 choices Exacute(+Dread) Realease(+Chivalry) Ransome(+Dread) and if you took over a city you had another 3 Sack City(+Dread) Occupy(+Chivalry) Exterminate Population(+Dread) well in any case you still get the city just if you sack it you get extra cash and the population is definatly gonna be unhappy.If you Exterminate the population its not so likely to revolt since most who would revolt are dead the rest are to scared to revolt.If you occupy the population is still likely to revolt and you dont get extra cash just you get some Chivalry well good guy points basicly.
This would be cool in ElementaL what do you think?
