ok I am really tired of seeing people saying that humans are underpowered :x The reason they seem underpowered is because over 50% of public players lack the disipline and skill needed to play them correct. contrary to common belief the way to play humans is not to sit in your base and let the goon pick you off one by one... you need to play more aggressively and chase those goons so they don't dare come near your base.... you need to destroy the alien team before they hit stage 3 as the human advantage is strongest in stage 2.
goons are not all powerful and dretches suck balls because though they dish out a lot of damage the humans with half a brain can kill them with absurd ease. DRETCHES FEEEED they are not something you should be throwing wave after wave at the enemy. yes the aliens do win alot according to the statistics but have you ever seen a co-ordinated human team?it is a fucking massacre!
the reason the aliens win is because the good players like aliens when they don't have a few friends nearby who they can teamup with... it is just more common that good players happen to be playing alone and not in groups, if you see 1 uber gamer join humans chances are 1 or 2 more will also join em and any1 caught on the alien team is in for a world of hurt pretty much regardless of their skill level.
2-3 teamworking humans can't really be countered in public play. try getting together a lasgun a shotgun and a pulse rifle in stage 2 and see how well the aliens do.
In large part I agree with you - I also think the 'pro-balanced' and 'pro-alien' side is forgetting one large thing: self-supporting alien bases.
The pro level human team will definately get out there and kill the bugs easily at s2, there's no justifiable reason for them not to. What happens, and this may be a map design flaw, (maps like Transit this problem is blatantly obvious) is that hunting down and finishing the aliens off is a 5-10 minute process on certain maps, and by that time even sub-standard aliens have reached s3. (because there's always that weakest link, you have to account for it)
This is also apparent in SD for different reasons. All the aliens need is a functional egg. That's it. These can be put up anywhere, almost anytime, as long as the 'control' structure is up. These two structures by themselves give you an alien team with full offensive capabilities, minus a booster. Humans need an armoury, medistation, and spawns can only be built in one spot, not to mention aliens have radar on even the suckiest alien players.
Having one active builder almost guarantees aliens make it to s3, assuming some semblance of team balance. No human stealthy egg-attacks, because the grangar can warn, or he can just go and hide some eggs, more grangars spawn, and this continues until s3.
Now every human team bar the most elite team-workers will have little chance against this defense. On some maps, such as ATCS, there are few places to hide, and by and large this is the most played map simply because it is the most balanced. I don't know if this is a cry out to the devs or the map makers, but this is the largest issue in my mind.
