True Vault Hunter Mode has been kind of strange up to this point... I had some difficulties before a point that I can't remember, then I just cruised along until I got to Overlook... then again, those Hot Loaders/EXP Loaders can be a pain... especially since I can't just go into Decepti0n and kill them with my melee (which works quite well now, because I have the skill that means that my holographic decoy explodes when I become visible, but, it also explodes when I deploy a new one with Many Must Fall, which has helped quite a bit). Haven't played any of the DLC yet because I should probably finish True Vault Hunter Mode before doing it.
I have looted a few oranges before, but they were never as good as the weapon that I had equipped before... the only thing I have never had at higher than a green rarity is a class mod... may have had a blue at some point, but I'm pretty sure I haven't. I don't think that I have had a relic higher than a blue either. I have seen high rarity class mods, but it was when I couldn't afford them (which means three things; 1. die less, 2. don't blow all your money on slot machines before checking the store, 3. always check how much longer until the item of the day changes, if it isn't too long, wait), I could've had an amazing class mod if I happened to have either 140,000 or 240,000 (can't remember which, think it was the former).
