Boss justifications.

Why is the warden not a boss but has 500 hp and the Wither has 150 while the ? The warden should not be considered a boss because of these reasons

1. It isn't supposed to be encounted

2. It can be farmed easily

3. It would be less mysterious if it had a huge boss bar

Instead the elder guardian would be a boss possibly because the ender dragons is the ends boss, the Wither is the nether's boss, and the overworld has none so far, it fits in because it has an army when encountered like the others, I resent the fact that the warden is being thought of being a boss.
