The reason is that it was like that in classic renegade and it was good that way.
and your answer to the second question is yes.
The blue circle is has a larger diameter than the length of a medium tank, that is pretty far ... but still easy avoidable.
The green one has a radius that is like the length of a medium tank, thats very far ... but fairly avoidable.
Thats what it is all about ... make it more easy to see for gdi and make nod sbh more carefully but keep
the stealth advantage to nod cuz they still can avoid beeing seen.
The blue one could be smaller but sure the green one should not be bigger ...
For stanks it should be the same range ...
i mean, gdi is wandering around the map, so it will be very hard for stanks to get somewhere undetected if that radius would be bigger than the green one ... that would make stanks rediculus useless, specialy with their low speed and slower firerate they have now
and Tactix is absolutely right there!
