As it stands, matches are too fast, and predator is forced to fight quick rather than stalk.
-More predator heals, whether through increased/quicker medkits, or more consistent pig spawns.
-Reinforcements, Remove predator notifcation about reinforcements happening, however increase the time from 15 seconds to 45-60 seconds. Let us hunt.
-Decreased fireteam gear that can be brought in, more reliance on equipment on map. This will encourage predator to trap gear.
-Predator second wind leaping. Predator needs to be able to get up high and make better use of his second wind.
-Increased AI enemies, aside from my suggestion in another post to remove hud elements on the fireteam that tell them where enemies are at all times, also increase the number of AI that are at bases by default, as well as the reinforcements called by the alarm. make enemies continue to spawn at bases until alarm is shut off.
-more objectives, increased match length. I suggest 30 minutes, If you must have a limit, but I would prefer the game simply lasts until predator has hunted all of the fireteam, or they extract.
