100-125 meters like you have stated is too much. I will list reasons why and give pros and cons to both sides to be non biased.
First and the biggest con is this will allow players to sniper abuse the game. The distance you suggested is a little to much. Best example is Derailed building with the trains on the inside with the easy access roof. Every roof and basically line of sight is within that 125 meter range. This will take the Predators ability to counter the roof camp because its out of maximum potential damage range for any of the pred weapons.
Pc will be easily dodged, Bow is less likely to land shots at great distances , smart disc is rendered useless at that range. Combi throw you run the risk of losing the weapon. Hand held caster is useless at that range.
These cons outweigh the pros for the Pred at that range. The pred will not be able to counter said camp, the Pred will not be able to hide approach.
Now what others and Myself have suggested @Coffee2Go and others is 60-80 meters I would like middle ground at 70-75 but not about what I want but is balance.
This range of the Pred being visible while being cloaked will stop the foolish that is cloak atm and here is why I think in my non biased opinion why.
The preds weapons all of the are now in maximum potential range. But are still counter able.
Pc can be deadly at this range but is also dodge able and counter able.
Bow is deadly at this range but is counter able by a normal team. Ie randoms.
The smart disc is within its range but is highly counter able and very punishable at this range
Spear throw less likely to be lost.
The pred can hide approach at the right angle. The pred is more visible within this range while being cloaked so randoms will be able to counter the attacks if any.
