One of EVE's sayings is "Don't fly what you can't lose."

In general, you get that kind of ship especially for these types of fights. There isn't much base-building or PvE inside of EVE; it's all about the PvP. Being able to say that you flew a Titan into a battle is a major accomplishment inside of the EVE universe, so you don't care as much if you lose it (of course, you want to keep it safe, but only to fly it into more battles).
