Small Railguns need to not be nerfed against installations any more. Not 100% sure if that was improved in the last hotfix, but they weren't working right after Uprising first showed up. Also, Railguns in general need to be instant-hit. The projectiles are supposed to travel at 7000 m/s. If that's true, then the shots that take half a second to reach the target are travelling 3.5 km, and I'm pretty sure clones aren't taller than Gundams.

Missile turrets need their splash radius back, but I VERY STRONGLY disagree with tripling their range. Why? Because Dropships aren't the only vehicles in the game. Triple range means triple the direct-fire range of ground-based vehicles. LAVs hitting from across the map is broken. Super Sniper Missile Tanks making a comeback wouldn't be a good thing.

What I WOULDN'T object to is a 50% base range increase on missiles, AND a 50% bonus to range on all weapons mounted on Dropships. Or they could tie it to the basic Dorpship skill, 10% range increase per level. Or do both, have a 25% range increase, and a skill that gives +5% per level. That would introduce stacking and make the multiplier go a little higher than a 50% increase.

Splash definitely needs an increase, but I'd say try it with 20 - 30% first, see how it goes, THEN look at maybe increasing it. The problems with CCP nerfing things are because they change EVERYTHING in a weapon's stats all at once (reduce direct damage, reduce splash damage, reduce splash radius, reduce range, increase scatter), and changing everything at once means you don't get to measure how big each individual change was. Suggesting significant changes to more than one aspect of a weapon will just swing it too far the other way and get it beaten down by the nerf hammer again.

Missiles
+range (50%)
+splash (20%)

Dropships
+range (up to ~50% with a skill to train)

Two changes, one significant, one smaller.

railguns still has about 3-4 x the range of all other vehicle turrents.
