There are definitely several spots that you can place the rainmaker that make it very hard for the enemy to get to. You can simply leave the rainmaker alive in a secluded area (think places that have only one route to enter.) With the rainmaker, getting splatted by the enemy in these areas is a large blow to them as trying to take the route to get there is mostly no man's land.
@KTKres The evidence I had provided did not have much to do with stall points at the base, including the possibility of being splatted. It was early on in the process and we were mostly searching for different stall points that could break the mode. With further testing I can see that doing it at your base is the most effective way to stall (Provided that you are splatted by the enemy) as you spawn right there and the area can be very tough for them to get to.
Some of these areas off the top of my head: (Could refer to @Agosta44 map post)
-Arowana's grate or mini ledge before the hallway
-Walleye elbows, or mini ledge before the hallway
-Flounder heights, top of the buildings (the straight, thin platforms that you can climb from your side)
The only thing the enemy could do is wait for the rainmaker to explode, or just try to establish map control (while at the same time letting it explode at the 60 second mark) The enemy should not aim to splat the carrier at the isolated area, making it harder for them to get there. (similar to what @Hitzel had said) It is the enemy team's fault for splatting the rainmaker in a bad area, this can be prevented.
With this in mind, I feel that rainmaker shouldn't be written off yet.
tl;dr: Enemy can stall rainmaker, if you splat the rainmaker in a bad area. Other than that, wait 60 seconds and try to gain map control. (if they try to stall)
