All missiles w/o extra missile can run out, Megas. As for Cyclones running out especially fast, I don't agree.
They last 100 seconds compared to Hurricane's 150 and Squall's... hovewer long that even is. 160? I think only Hammers and Dragonfires run out faster than Cyclone.
That is in such a massive vacuum and you know it, dude. Who spams Cyclones nonstop? No one, you time properly. Who spams Squalls and Hurricanes? Everyone—these are longer range missiles you usually just toss out there. Haha, how about we increase the refire delay on Cyclone to 20 seconds? Wow, it now lasts 200 seconds! Now it's better right?
Besides, you get 80,000 damage out of the Cyclone in a vacuum, 35,000 out of Hurricane (lol) and 16,000 out of Squall (looooool) and even if every Squall hits a shield it still only does 40,000 max damage.
