Wow a ton of people here really hate the INS team. Honestly this forum has gotten worse and worse over the years. If it isn't RO, it's FLAME TIME!!!!
Really, grab an M4 (so you can see all around your point of aim) and fire just around a target. You'll notice that the hitboxes are very accurate and there is no issue with them. And people here are complaining about the movement in INS? Have you EVER played RO? Due to the nature of the Unreal engine, the movement in RO is some of the clunkiest I've ever witnessed. INS feels much more like moving about in real life. I never have issues going where I want to go, and not feeling like a robot doing it.
And as to the suppressing fire issue, I think you must be the only person in the RO community who feels that it works. You seem to think the same actually, when you say that no one else uses suppressing fire. I've been here since beta 1.0, and I can tell you why no one uses it...
it doesn't work!
I can keep an area hosed with fire from an MG42, and a rifleman will simply duck behind cover, aim, pop up, and fire. Immediate accurate fire, and I'm dead. And if you think SMGs can do the job, you're insane. Trying to hose an area with a PPSH is impossible due to recoil, unless you are laying prone AND supported, it just isn't going to happen.
Really people, grow up. Stop flaming this game because it isn't RO. I didn't like it during beta 1.0 due to the horrible FPS, crashing and TK issues, but with 1.1 the game feels good, plays smoothly, and has a fear of death unlike any other I've played (except maybe AA, but 10 minute rounds tend to do that). It isn't RO and that's fine, they are both enjoyable. I commend the INS team for releasing a high quality HL2 mod FINALLY, I've been waiting a long time for that.
