Problem: orcas in small groups will sometimes get in each other's way and be stuck outside of range. The old range was 5, but this was to nerf large groups.
Orcas have been nerfed in several ways. One of the ways was to reduce their range from 5 to 4. However, when the range reduction is coupled with all the other nerfs, it seems a bit too much. Orcas are fairly vulnerable now that air defense has improved.
Someone complained that there was not good warning for the nuke. All you heard was the launch sound, which wasn't that noticeable and a bit like other sounds.
Now it says, "nuclear missile approaching".
Increased ROF of tanks. The guns of Light & Medium Tanks are a bit weak
relative to their role as tanks. They do less damage than bike rockets,
and do less damage against light vehicles than even the hum-vee. Changing
ROF should mitigate this a bit, even though their gun is still not that
powerful (e.g. compared to stealth tank, and even flame tank matched light
tank). The fact that their rivals are often moving fasts also complicates
the slower ROF.
The same proportion of damage was kept between light & medium tanks.
Mammoth Tank was left unchanged.
Reload period for orca inreased. Fully reloading is roughly equal to the amount of time it would take to go from the center of an 80x80 map to your home base, land, reload, and return to the center. (About 30 seconds).
There is +1 rocket than before, because each rocket has been weakened. This makes the orca take longer to unleash its full payload.
This is combined with slightly reducing the amount of tiberium stored in Refineries. Part of the reason for this is that refineries are targeted lots by ion cannons (one-shot kill) and nukes. Whenever this happens, you lose the money that's in them. By making a silo that stores more, you can store the tib farther away and keep a bit more of it safe.
The other part of the reason is to bring silos into the game as a somewhat strategic structure. By having more money, they are more capturable, because you can steal what's in them. It might also make sense to maybe airstrike them so that the opponent loses what money is in them.
The way to counteract this problem is to build more silos. They cost a bit more though (double) so that you have to think about how many you want.
