Unfortunately, I have been pretty busy lately, so I haven't had much chance to actually play NS2 for maybe 2 weeks
So it's a bit hard to say right now if it's a good change or not. I've read the patch notes, and they changed a lot of stuff. It does seem to favor marines a bit when reading, but I'll have to play 250 to get a better idea.
Problem with NS2 is it's so difficult to balance properly. And a bit like Starcraft, just changing a few values here and there can affect the whole game a lot. I'm glad I'm not on the design team. I'm also a bit concerned about the decreasing player base. I keep looking at the steam stats, and every day, it seems to be going down. I hope the devs will do something, besides free weekends/sales as these events justs boost player count for a week and then it's over.
And maybe it's nostalgia talking, but I think I remember having more fun in NS1... maybe because it was a mod still in development and they were adding more and more features each time, a bit like the CounterStrike betas of the past. Ah well
