Some great ideas here Thefty. But truly, you need to 1.9+ sweetie you're not an old man, move with the times ;p
Voting Options
I like your ideas for world events particularly that they are voteable for donators; makes my rank just a little more worth it's money.
Health Options
I like having health options in SG, it's something that is in most of CC games and makes it easier for those of us who have a comfort zone within another game to adapt when friends request alternative games. I'm also a fan of half health as it suits my fighting style and creates a disadvantage to others not used to playing it.
Kits
I like the variety of your suggested kits and they look balanced as others have also agreed that these need tweaking.
Items
Totally agree, there needs to be a way to heal in hardcore mode but this ability should be rare. Otherwise, you may as well play a different mode like OP.
Maps
NEW MAPS EVERYWHERE PLEASE, not just SG. I'd like to see more maps as a priority as I'm getting bored with the map selections which makes me bored with the games and being a person with little patience it makes me wonder off to do other things. I would like more 6 player team games as there are few options for this and those with ranks can have greater numbers in their parties so it makes the party option difficult to manage on occasions.
Lobbies
Different waiting lobbies would be interesting however I'd rather other suggestions are prioritised. Maybe just change the parkours every now and again.
Thanks x
