Borderlands 2 after level 30 [closed]

Crazy Earl no longer has anything to sell, why am I still getting eridium? Is there another E vendor?

No, but Terramorphous costs 4 and both Hyperius and Master Gee cost 8 each.

What is the best course of action if I wish to continue to play the game?

If you want to continue levelling you need to move on to TVH mode. You can always switch back later to complete all the side missions and challenges

Where should I go to find places with loot that are level 30 and above?

Playthrough 1 is capped at 30, though you might see the odd 31/32 in tough areas. You need TVH mode.

The 3 raid bosses are always level 50, but you won't scratch them at level 30 and you won't level up to 50 in 30 areas.

I really like playing and wish to continue, but is there any way to do so without going to true vault hunter mode?

Not really, though you could start a new character.

If I do go to True Vault Hunter mode, do the levels start at level thirty?

Yes, enemies in TVH scale from 30-50 and the missions reset. You can switch between TVH and normal mode in the character selection dialog, and you keep all your kit between the two.

You have nothing to lose going to TVH mode, as you can always go back, and its the only way to gain levels. Also the gameplay changes - using the right elemental type becomes much more important and ammo becomes very expensive, so it's a new challenge.

If you start the second play through, which is what they are calling Vault Hunter mode, then you will start at the current level you are now and all the areas scale from there normally. Your character will keep all stats and all weapons they have on them. From that point you should be able to get to the level cap by your second play through.
