I've gotten TF2 a day after launch (after much trouble with Steam). I played it, found it fun. Then I met sentry guns. Then I tried playing again. And again. I guess I gave up tonight.
Sentry guns are incredibly, horribly overpowered, and can totally ruin the fluidness of a game, turning almost every match into a stupid contest of "lets just play here in this area until hopefully one of them blows up". Sure, they're manageable on their basic level, but how often do you see those?
- A sentry will react in approximately half a second. So sneaking on it is pretty much out of the question.
- It will kill a soldier in, at best, three seconds, usually less. A heavy I don't know, probably not that much more. Any other class is basically toast as soon as you walk into the range of one.
- It will take FOUR soldier rockets to destroy. And, as you can guess, by the time they're all fired, you're dead. If you're lucky to have a corner covering you, you can strafe, shoot, then strafe back. But you'll still get hit, and we're assuming the engineer there is ignoring you.
But "wait", you say. "You can go as demoman". Yeah sure. The only problem is, you can't really go on attacking as a demo, you'll die before even getting to the sentry. "How about spy? They can disable sentries". Suuure... if you're disguised, as the disabling thingie (Sapper?) won't work if you're cloaked. And any engineer worth his salt will spot you immediately. "Ah, just go in as soldier and shoot it!" -> see above points.
In sum, one has to be either very lucky or in a very specific situation in order to do anything about them. Which is almost never. Of course, teamwork will work, but come on, even counting on one or two teammates, how often do you see a single undefended sentry?
I dunno... maybe other people had more luck with their team playing synchronized and whatnot. Just about every match that I played where a couple sentries were laid down just turned into "chicken-and-egg", boring, deadlock games.
I'm not against the concept itself, it's a good idea. But the guns can't react so fast and kill so fast in order for a player to have a reasonable chance against one.
