120s cooldown on helis/attack vehicles should not be put in place in conquest

@SpudBug

Maybe and if so it was too fast there too (despite the insta- vehicle-respawn servers).
I would consider 2 minutes OK and taking out a tank would then have finally some impact.
Overall, a good change in my book.

And as far as your statement "a 120 second cooldown on the Jet/NB/Attack heli means the enemy team gets two minutes to farm infantry without worrying about other aircraft contesting them. " is concerned: Last time I played it was definitely NOT our helis that were killing the other helis as they were busy with their own kill streaks on the enemy infantry.
As long as we have SOFLAM and M5 we as infantry can at least drive the enemy helis off.

@SpudBug One of the additional settings on our Friendly Fire enabled Classic BF4 servers was 400% vehicle respawn time. And in my opinion, that was a good way to set it up. So 2/3 vehicles double respawn time is something I like to experience first. But it seems to go in the right direction.
