In other words, it allows more reasons to be randomly banned, long downloads, more chaos, random kicks for ping, and a place to listen to people scream "bullstuff" after every kill. Nice!
1. Being randomly banned depends on the server, if you get banned/kicked look at the reason for which you were kicked/banned and LEARN from your mistake or FIND A BETTER SERVER.
2. Long downloads? If you play mods for COD4, normal people would download them from the internet, not the server. Most players play on unmodified COD4 servers that don't require and downloading.(map load time on PC is also a fraction of the time it takes on consoles) Other games that actually do require you to download things only make you do it once most of the time assuming you continue going to that server, then you stay in the server for hours assuming you find a good server, if its a bad server LEAVE AND FIND A BETTER SERVER AND BOOKMARK IT.
3. Kicking people for pings that are too high makes it better for everyone. It prevents laggy people from having an advantage/disadvantage compared to the people whose ping's are within reasonable limits. If you get kicked for high ping find out why your lagging or FIND A LESS LAGGY SERVER.
4. Most servers don't actually have 64 people in them at once because yes, most people don't like that, but for those who actually enjoy playing like that AT LEAST THERE IS THE OPTION TO.
5. In my experience as long as you stick to good servers with admins or servers without voice chat enabled, people are much less likely to spam the mic with obscenities, if they do they get kicked. You could also disable voice chat output so you don't hear anything people say , which is a simple alternative to having to listen to 5 year olds scream into their mics.
I agree with this, I'm most likely just going to rent it.
I'm pretty sure that you wont be able to rent it for PC because its being integrated with STEAM
