(i know my english is not good )
1) I think the "Q" function should be removed. It makes it to easy to say where the nuke is. In old Renegade you had to know the commands ctrl + alt + number. Many people didnt know that and this separates pros from noobs (Its also too easy to say repair building "x" if someone attacks it with tanks or c4)
Now the half GDI team comes do disarm nukes or repair buildings...
2) Engi disarms it to slow and hotti to fast. The remote c4 hurts to much in combination with sprint.
3) Even if Nod plants 3 nukes at the same time they are often disarmed (on 30-40 player servers / old Renegade at least one did it)
4) Stealth effect should be light red so people can see them better. Mobi and hotti should NOT see them from far away - i personally hate that 0 skill fuc*in campers which cant play tanks and camp inside their base.
5) And nuke should be disarmable till 0 seconds (so 10 seconds less time - that makes it more exciting).
3.....2.....1 nuke has been disarmed or multikill/ultrakill
6) Other things that should be changed: Medium Tank should have longer range (20 - 30%). Stank should be easier to play (old renegade had nearly flat ground it was not that hard to hit a target with stanks if someone is in front of you). APCs with more HPs or better armor vs humvees/rocket soldiers. Tanks should be able to hit apaches/orcas if they fly over them (not 100% over them, but more than now). Apaches/orcas need better armor vs snipers/rocket soldiers. Autoaim of rocket soldiers and mrls should be weaker. Mc Fartland needs a new name and weaker bullets.
