If you are looking for the ultimate Borderlands the Pre-Sequel experience than check out the BLTPS Community Patch.
So if you want the ultimate Borderlands 2 experience check out the Borderlands 2 UCP. Since then balance changes have been made, new loot drop locations have been added, and new visual skins for certain weapons have been added. This way under-performing skills got a small boost to make them viable for late game and provide new options for interesting builds. With the second patch, the community started addressing the skill trees of the various vault hunters. The first community patch buffed certain gear and made things like Seraph crystals an auto pick up. The local file which contains the community updates will fix certain gameplay issues and enrich your experience. By tricking the hotfix update process data will now be loaded in from a local file instead of the Borderlands servers.
With feedback from the community, some badasses have created an unofficial community patch for Borderlands 2 to make the game even more badass.
