I think helmet is a bit cheap for what it does.
I mean, the radar and headshot protection.
Usually, in 1.1, a lot of matches ends with hs3 and as1/2 very soon, cuz the aliens usually feed at start and humans get s2 too quickly.
And now, if the human team have medium-skilled lasgunners or massdrivers aliens are lost. Only with a lot of luck they can get s3 too and win, but thats a hard thing.
So I think making it a bit expensive can balance somehow.
And also, I was thinking in something like... separate radar and helmet.
And 2 radars, the normal radar and the advanced radar.
The difference is the scanning speed (and maybe the area to scan?) , being faster in the advanced.
Waring helmet you cant use both, but with bsuit, you're unable to use the advanced.
And the reason for this, is the possibility to buy the helmet and if you dont need/want radar, save some money.
And if you want a more effective rdar, wate some more money.
