Firstly (and I don't mean to come off as anal), I'd like to request discussion pertaining to Reaction Fire be split into another topic. Secondly, I'm glad that this issue is being more actively discussed on the forum; this is a good thing, however it needs to be done in a thread more pertinent to it. That said, I'd like to review some of the proposals on the matter:
I think it would be good to have a small recon robot, which could not carry weapons. It would be small (hard to hit) and have moderate speed. Think remote control car - or perhaps moon rover. i think 6 wheels would be good.
This recon robot would enable reduced risk exploration. You could find the snipers and then take them out with grenades etc. This should be another way to take the tactical advantage away from campers.
Scouting drones, or something like them is being considered (I think). I am not certain whether it will be ultimately included. This would definitely help address the problem by locating RFers so they can be attacked via indirect munitions and splash damage (grenades/parabolic trajectory weapons/etc...).
1. keep precision (even increase it) but drastically reduce the sight of soldiers having reaction fire set on (they would for instance react and fire at only one direction or one set point (ex a doorway).
2. Restrict number of soldiers having reaction fire set on to two per round.
3. Restrict RF to only assault and close assaulting weapons ex: pistols, pump action, machine gun etc... (this seems already being done in 2.1.1 for ex for rocket launcher)
#1: Not realistic. Precision should if anything, decrease as a consequence of reaction fire.
#2: Arbitrary restrictions are poor ones. The solution should make logical sense. That aside, RF is still extremely powerful even if restricted in this way.
#3: I agree with this. Only weapons that can be quickly discharged/employed should be permitted to exploit RF. I do not agree however, with restricting RF on all explosive weaponry as has been done. If it's plausible for an explosive to be used in RF, that explosive should be permitted to benefit from it. To the people who would counter that RF on a grenade launcher (as an example) might be devastating in terms of friendly fire: if this risk is considerable, deactivate RF for your grenadier.
Reaction fire is exactly that... it's a reaction. You're not really checking your target other then finding a moving something.
Have an intelligence (or other stat) based possibility of shooting ANYTHING that suddenly comes into view. Friendly. Civilian. Alien. Your ability to comprehend quickly enough friend or foe when you're amped on adreniline is kinda low.
Perhaps have two settings for RF... Hyper sensitive or Target Confirmation... and lower Target Confirmation's ability to fire before the main player's.
I'm not sure if I agree with this suggestion. The discrepancy in appearance between aliens and humans is obvious to such an extent that you'd probably be able to determine the difference immediately.
Personally I prefer restricting RF to certain weapons and firemodes (snap shot/burst/full auto and similar variants), and having TU comparisons impact checks to determine whether or not Reaction Fire is triggered. After all the more "occupied" your soldier is over a given period of time (as demonstrated by remaining TUs) the less likely his actions are to preceed those of someone not so distracted/busied.
