This idealism just makes the game very unbalanced depending on whether the map has base defenses. It would be obvious that if this were the case, GDI would always win whenever there are base defenses since Nod essentially has no advantage. Case in point, how many Field games have been won by Nod in Ren X?
Thus in Renegade the devs made the artillery very powerful, enough to stand against GDI vehicles. Unfortunately it was a bit too powerful and it made GDI tanks look bad in comparison. As a result, in the original Ren Nod won more often on maps with base defenses.
But Ren X players like to play defenseless maps. Just look at the leaderboard, Nod has much higher win % than GDI. It wasn't this bad in the original Ren.
What the Ren X devs wanted to do is exactly what was in the quote, that is make sure GDI has better vehicular firepower and Nod focuses on stealth. Thus they buffed the sbh (possibly unintentionally), nerfed the artillery, and buffed GDI vehicles.
It sort of backfired because the game is less balanced now.
Jelly server has increased the price of sbh to 1000 due to the sprint feature and the lower view distance.
