So I've played quite a lot of FFAs and enjoyed quite a lot of them recently. However, it seems that on any map where you can get 80+ metal per second, the safest strategy seems to be to rush a starlight.
It makes quite a lot of sense: why spend actions expanding and fighting, when you can settle in, make singus and then rush a starlight.
Starlight costs 45k. If you can push 100 metal/second to it, you can make it in 7.5 minutes. For what it can do, there is no reason not to build it if you have the economy. (+ 10k of units to defend it, but since you aren't attacking, then you will have that army.)
Starlight used to have weaknesses:
It could be blocked with a large amount of shields
It could be blocked with a terraformed building
It used to have less range (I think?)
Now it's a glorified I win button. I mean, it's supposed to be, but it's way more effective at destruction then the other superweapons. I've had 2 games this week where my finished Starlight got zapped by the enemy Starlight because they finished it less then 20 seconds earlier. There's no way to block the Starlight beam even for 30 seconds. It's also much more effective then Zenith or DRP and it hard-counters them.
Now, while I think it should get nerfed, I don't know what would be the best way of going about it.
What I want is for the interval between "Starlight turns on" and "All opposition is dead, resign already" to be a little longer. Right now it can be as low as 30 seconds. My point is that it's a lot longer for other supers and it gives more time to react to them.
