I don't know anything about the mechanics of gameplay, but I find myself agreeing with some of what briach says.
It's simply wrong (and a form of elitism) to say that combos are "too" easy to do in 2k4 and that noobs are running around with mini deemers killing better players without having to use any skill.
Reading what T2A said above and I can kind of feel myself agreeing with that. I only came to the game with UT2k4 so I can't make any comparisons with other UTs, but I have been playing this game exclusively for 2 years now, so I think I no longer qualify as a noob.
Like T2A, shock combo kills are extremely rare for me (unless it is against a genuine new player who doesn't know how to dodge) because anyone with a degree of experience at UT2k4 is usually better at getting out of the way than I am at killing them with a combo.
Perhaps for people who've been playing this game for 6 years or whatever, and who learned combos on the (more difficult?) UT, then they are really easy to do and kill people with....But that is certainly not true for the casual gamer.
Lets not forget that it is the casual gamer that UT2k7 has to appeal to. Epic have claimed that they thought UT2k4 was a failure in terms of numbers of people playing. 2k7 HAS to get more players in, and I personally would love to see more players, more NEW players on the servers.
That's not going to happen if the shock rifle is made even harder. The shock rifle is already a little unbalanced because of it's high rof and the pushback effect...It is pretty much the strongest weapon in the game and one that more experienced players can already dominate new players with. To make the combo even harder to pull will for sure keep the hardcore players happy....but pretty soon the new players will turn away in droves. As briach pointed out, there is simply so much competition now, if a game is simply too hard for a new player to get a foot on the ladder, then they won't stick with it.
I'm not saying that things should be nerfed. I've played 2k4 for so long because I love it's sophistication, I love the fact that I still need to develop and hone new skills. I work full time and have a busy social life and don't have much time to dedicate to getting good at a game, but 2k4 kept me coming back because I liked it enough to want to learn (that and the fact that I own a Mac and there aren't many other games worth playing on Mac
)....
...but for gawdsake don't make it harder. It will kill the game.
