Honestly I see a lot of speculating but not much action.
Albeit, I shall speculate myself...
1)ETG has a problem, the problem needs a solution.
1a)Stagnant meta-game
1b)dwindling interest
1c)limited ability to make changes
1d)limited medium to solve the above
2)--because of 1d, it is difficult to find a solution--
Our primary source of change at this time is the implementation and/or changing of cards.
First and foremost I recommend absorbing the suggested changes section into the CIA section, I've long been confused as to why these are separated as they both have large impacts on one another. Separating the two only creates more opportunity for imbalance which is ironic considering the whole point of the suggested changes section is to better balance the game.
Now from my own perspective, I believe we could redesign the way CIA works.
I've personally seen many confusing voting trends which often leave great ideas falling into oblivion while many semi-good and some outright bad ideas get tons of praise.
There are two key points at issue here, the current voting system is ineffective at reflecting what cards would be a good addition and/or modification to the current game; and the community itself which uses this system often seems uninformed.
Because everyone has an equal chance at voting, there lies an issue with people voting based on quick decisions, face value, pretty mechanics, etc. I honestly believe that too few people take their time to break down the card and determine how it would impact the game.
To be perfectly honest, I imagine everyone is guilty of this to some degree, it's hard to avoid.
The other issue as that this same trend that impacts voting impacts card designers as well(grudgingly admitted I'm heavily guilty of this). Too many ideas are spur the moment and while they may have nice initial appeal they often fall apart after careful consideration(unfortunately this also negatively impacts creative thinking, I personally design cards purely for fun, but it hurts to see nothing good come of it). Unfortunately the current system allows such ideas to pass through un-phased as long as they follow proper formatting.
Rant aside I think the biggest impact we could have currently would be to redesign the way the CIA section works.
1)Some better/stricter regulations need to be placed on cards entering the first level of voting, while it was improved when the number of weekly submissions was limited, I feel it could be improved more.
2)I recommend a two-party voting system. One where anyone in the community may vote and one where a select council votes. Card progression propagates as a culmination of the two.
But more than anything, I fiercely believe we need somewhere to really debate these changes and perhaps design a new system outside of these forums. I recall the card idea round table(i believe that was close to the name) in which a lot was discussed and quite a few ideas brought to light. It was also enlightening to me personally. I thank OT and ZB for personally giving me a very different perspective of the game. I've always treated this game as an aside but they showed me just what it means to really care about the direction this game is growing in.
If someone could set up a similar such board and organize it I believe we could really get down to making something happen(I'd do so myself but my voice is significantly smaller and my knowledge limited in scope).
