• weapon balancing: Most people seem to thing the game is very well balanced, with only a few weapons being out of line with the rest. There is a very widespread usage of weapons and kits, which shows people aren't gravitating to just a few specific OP things.
• new weapons: I personally think there are plenty of weapons, unless you're coming from a game that has so many weapons that you can barely tell the difference between them. More weapons would also make the issue you think there is with weapon balancing worse.
• weapon attachments: they could be neat depending on how they're done, but could again affect the issue you think there is with weapon balancing.
• Pulse Blade: I guess it's not easy to destroy if you see where it is? I'm not sure because most of the time when I get pulsed I just do my best to get away from the area of effect. I honestly don't see it used a whole lot anymore.
• Factions: they're just fluff, and a different way to help you unlock some stuff if you swap around to different ones depending on how far they are from leveling. Basically just a fun cosmetic thing.
• Better descriptions on things is never a bad idea.
• What tacticals are you referring to that need balancing?
• Coliseum is just as pointless as any other game mode. The peoople that like it play it and have fun, the people that don't like it don't play it. It's the same thing as me saying all the modes I don't like are pointless.
• I honestly have no idea how anyone thinks a game that has a fantastic single player campaign and fantastic multiplayer seems half finished, especially when you don't actually say in what way it seems half finished. Unless that comment comes from your previous points, many of which I don't personally agree with.

Now it'sa good game but it definitely needs some work.

Well yeah, even the best games need work, and there is definitely room for improvement in TF|2, I'm just not sure TF|2 needs the improvements you're implying, as it seems like you want to turn TF|2 into one of the other more popular shooters.
