Pred weapons first. As it stands, predator weapons need to all fill a roll.
-Shoulder Cannon, Increase damage of non charged shots slightly, otherwise, solid.
-Wrist blades, Faster swings. Otherwise They are perfect
-Elder sword/netgun are solid.
-Handheld Plasma caster. Where do we begin. Damage buff, but severe drop off. It should hit like a truck when used point blank, but at any range it should drop off significantly, this would make it a good counter to the knife parry/spam, while not making the bow/shoulder cannon useless.
-Smart disc, Remove the ability to even control it. Its not fun and more often than not its frustrating with the ping issues. Instead create a lock on feature, throw it, and it hits a target then tries its best to come back. Otherwise, if you want to keep it as is, significantly increase the range, and turn rate.
-War club, make it break through parries, keep everything else the same.
-Bow, Allow us to hold it fully charged indefinitely. Otherwise its solid.
-Combistick, Once everything else is buffed, I suggest nerfing its damage slightly. As it stands right now its the best of every world, and should be a jack of all trades, rather than a master of all trades.
Fireteam, First off, friendly fire, nuff said. Not gonna cover most weapons as they are all solid, except a few outliers. I think some of the assault rifles/smgs need a damage buff but thats not too important right now.
-Sniper rifles, specifically Sawz-50 and 7EN. Remove iron sights/red dot/holo sights. They should be as powerful as they are right now, but make it very difficult to use them at anything BUT range.
-Grenade launcher, Friendly fire. it needs it to prevent spam. If no friendly fire change, then tone down the screen shake from explosions significantly. Either this or friendly fire, or even both, would make it much more utility based.
-minigun, move to primary slot, otherwise its fine.
EDIT: Forgot to mention knife/suppresors
-Fireteam knife should consume stamina for each parry, that way they cannot indefinitely parry, but only prolong their lives enough for their teamates to save them. Knife damage should be reduced against predator as well as AI significantly. its far too reliable.
-Supressors for fireteam weapons should reduce said weapons damage output. This is to balance with the reduced noise for predator to track.
