1: Singles Vs Teams.
The primary issue with the consept of the humans being more powerful in teams and the aliens being more powerful in 1-on-1 is that not only does it make small game counts favor the aliens, but it also makes large game counts favor the humans, exclusivly. Additionally, it forces smaller maps to be favored by humans because the proximitry of the bases forces clogs in hallways which, in turn, would favor the humans. Large, spider-web like maps would favor the aliens because they would be more apt to attack single exploring players who are trying to locate eggspam or the alien installation.
This would be true 100% of the time, if and only if the humans didn't run out of ammo so darn quick. That's a major part of why they lose S3VS3 on large maps; you run into 2 or 3 guerilla attacks as a team and you're out.
It reminds me of an old RTS game called Total Annihilation whereas the ARM had the best bang-for-buck with level 1 units and therefor, was better able to rush the Core base during earlier stages and take territory during early stages of the game. One tank, the flash tank, was extremly effective on medium sized maps because you could rush the core and deprive them of resources.
Once the Core hit Level 2 units, the Arm was severly outgunned by the Cores larger tanks and better offensive structures. Between 2 evenly pitted players on a medium sized map inwhich both sides were identical, the core would win more often than not because of the better units.
More importantly, no game that anyone has played revolved strictly around teamplay; tribes is one such example of one of the most challenging game series out there and it strictly wasn't teamplay. Teamplay is important, but shouldn't be required to be in pubs. If it is, then a GUI such as what planetside has or even the voice chat system natrual selection has is required to give the team needing to organize a chance to do so.
2:
the battlesuit is never designed to go against tyrants, its more for suicide rushing against s2 aliens. The game is designed to give the human upper hand when they get s2 and aliens in s1 and s3.
Then how do you stop 5 tyrants in a 5V5 game?
You can't, that's the problem. You don't know where they are, and if you did, then you'd have to go at them 1 by 1. When the aliens have 5 tyrants, and the humans 5 battlesuits with luci cannons or whatever weapon the wielder wants, they still can't win against that many tyrants unless they're all coming from one direction. Then you can pretty much rifle them down 1 by 1 with 5 players. in an open area you're screwed.
The tyrants know where you are and are going to come in wave after wave and kick your butt. You can try defending, but in OT you're going to get bogged down and killed.
If I join Aliens, they win most of the game (as long as there aren't too many newbies in the team). Same is for Humans. If I join them, they'll win most of the games. It's all about skill, most humans simply don't attack the aliens' base. I always try to even take OM down in S1 (everytime with painsaw), and most of the time it works. If not in S1, then in S2 or S3.
You would imply that if you played against a team of skilled players, you'd always have the same outcome.
Did I mention the stats quoted includes all games played, including all scenario's whereas the humans/aliens were stacked and were even?
Another problem is that when the humans attack and start pwning in Stage 2, half the attack force turns around and heads back the second they hit Stage 3.
Then the good players eventually get overwhelmed and the noobs are the only ones with any money.
Usually the attack force turns around due to running out of ammo and the aliens really don't re-establish themselves. More importantly, if one team is near S3 then the other team usually is as well, and that means they have as many kills and therefor as many credits or evo points as the other to invest.
