Frankly, I don't think RA needs to be nerfed. Its a risky strategy to pursue, it leaves you vulnerable while getting it, and your not invincible when you DO get it if they raid your gates.
I think there's a consensus in general that yes, RA isn't overpowered on the small/medium maps, but that this is the case on the large/huge maps. It has been discussed to death, so I won't go into the finer details. Look to my previous suggestion on how ensure that RA is only "nerfed" with regards to the bigger maps. I'm not trying to get personal or anything, but man, I am tired of people saying RA isn't unbalanced due to the fact that it isn't unbeatable. Even if I for some strange reason decided to concede and say that RA isn't unbalanced, I would still want RA changed. RA simply isn't fun to play against, and diminishes several of the nuances of the game, just like the overpowered trade. And with regards to that:
Not to mention that since trade is so powerful, the Vasari are at a serious disadvantage against TEC and even Advent in the short/mid game. In my opinion, RA helps make the Vasari less worthless.
I've pretty much already replied to this:
I don't really care how RA is going to be "nerfed"´, as long as it is. As it stands now in 1.03, RA is only tolerable on the larger maps due to the combined unbalance of TEC trade and the black market. And you can't ignore one or the other without leaving the other overpowered. As it stands now, both TEC trade and RA detracts from the game experience.
Again, the unintendedly overpowered parts of each of the races' arsenals might somewhat balance eachother out, but they sure as hell also makes the game less fun. And that's why I'm playing, to have fun, not to win.
