The solution is to find a position that allows you a view into the site but also has an easy route to retreat. If you get a kill, great it's now a 2v2. If your teammate dies, it's 1v3, you have no armor and there's a long time left on the timer then maybe you should save some guns.
That's why people should carefully consider which bomb plant spot they choose, there are some that can be covered from strong defensive positions at the edge or outside of the site.
