Well, first of all, nice to see you back Seph. Good to see anold player come back, and give his input on the current things going on.
When we talk about balancing early games, I assume we are all thinking of Pie Chart, since that is the most played map. Some of the strats we(Me, Hawk & Seph) think about might be long forgotten, so we migth have an edge ortwo on the current players.
Here's my thinking on the subject:
As far as I can remember, I don't think I have lost a 1 vs 1 game(no mark, rushing) against a Eden player. At least not after I finished my training with Aslan(some of you might know the true identity of this player, but shh). Lets not go into tactics about how to beat a Eden player in no mark or defend as one. It is my statement here that I believe I won, if not all, most of my plymouth vs eden no mark games. That is my first arguement for for Ply > Eden rather than Ply = Eden in no mark games.
Secondly, I was among the top players back on WON(Hope I'm not bragging to much in this statement), and as far as I can remember I could give anyone a good fight by a quick rush. However to give Leviathan some credit here, he uses my tactics better than what I did and he pulls out his early vecs faster than I remember myself doing. So, basicly in any game where Lev choses to go for a rush(most of 'em), he will control the pace/direction of the game to a large extent. After getting a few severe beatings last year, I know I personally will not stand a chance as Eden vs Lev as Plymouth.
As Ron used to say; "Speed Kills" and Lev is damn fast
As for the point about Acids vs Thors, I've been trying to get people here to figure that out for some time. Acids is Edens greatest weapon, and personally, if I don't have to I rarely bother about researching Railguns.
