#1: I agree, the limited time I've actually gotten to play pred hunt I've found that gathering weapons takes some time, especially if you have a decent marine team, I need to plan my way around the map just to grab the spear or disc, by the time I do I have maybe 10-15 sec to attack and get a kill. Maybe bump the timer up to 50-60sec? Nothing huge just a little more time to plan your attack.
#2: Now this I'm not sure, I don't mind grabbing the weapons; I just need more time to do it. I think the only weapon I'd even consider fair to be spawned with is the spear since it takes a bit of skill and aiming.
#3: Agree here too, there needs to be some code that can spawn you in an isolated area to start off. I can't tell you the number of kills I got from a new pred popping up in the same room as me, he didn't have a prayer.
#4: No, I like that its one against many, that's the true Predator style.
