Idea : Remove Gold and EXP from Demigod kills (or at least give option in custom games to remove)
The one biggest thing that breaks this game is having a feeder, a bad player that wrecks your chances of winning.
This game is not enjoyable to play with a feeder on your side as you have no chance of your personal skill winning through.
Most successful online games have elements where even in losing you can still have enjoyment eg. racking up a good K:D ratio in Counterstrike despite being on the losing side. Or pulling off some good strategic moves in an RTS game despite losing.
Demigod is doomed, because you know as soon as that player goes 4-5 down, your chance of remaining competitive as a sole player is almost 0%.
Ways to balance this
I think that creeps should be increased in their XP and gold that they give, thereby increasing the importance of lane control and making up for the lost gold and XP through demigod death. Nothing drastic, just 1.5x or similar.
Death will mean you have control of the lane, the dead demigod is already at a loss without the burden of a massive gold boost.
Make death 45 seconds at least to discourage too much suicide.
If you are skillful enough to hold a lane, you can remain competitive against the other DGs, you will not be suddenly 5K behind in items. You will still get some personal satisfaction from holding your own, even the hope of turning it around, if your feeder can just stop dieing.
You don't get so much frustration from players at other players when they have a few deaths.
The game will be fun to play as there will be a lot more combat between players.
You don't get gold or xp anymore. There is an argument this will lead to less incentive to kill, however, this is a multiplayer killing game, the whole incentive is to rack your K:D ratio up. I would still be eager to take my opponent out even if I got no gold or xp. Just the pleasure of taking them out and having a lane to myself is enough.
Overall, I think it would be great to have this option in the custom game, at least to try it out, to see how it works.
It is very frustrating to have a player who feeds, or even to be the player feeding, I have had enough bad games where I have 3 avoidable deaths and have sealed the fate of my team.
There should be a penalty to death, however, the penalty at the moment I feel is too high and creates a lot of bad problems in the game. The whole PUG vs Pre-made revolves around this, removing the gold and xp from death would slow down steamrolling, players on the losing side would feel more inclined to stick around. Even if they are on a slippery slope, at least make that slippery slope enjoyable to play. At the moment, playing for 15 mins severly underpowered through no fault of your own is not fun.
