If you're talking about the Title "Entrace To the Demon Realm" you have to clear it in 4:30 which is totally possible considering runs can only be 2:30 with a good party and you don't even need a certain rank for it.
Titles seperated on a character is not such a huge issue to me since I mostly care about my main and I have Race Go for CE so thats a w/e to me. The game is about grinding just like the majority of KR MMO's thats how they succeed because they want to keep players occupied as long as possible and get as much money as possible out of them. PTH is best to farm if you can get 200~300 mobs per run which is possible you just need to be "geared enough" which is not much for Elrianode but its still better to get than Race Go. If you dont want to do PTH just get God of Dimensions its Henir Rank 1 of your character which means Solo = no F8 if I'm not wrong same Attack bonus and Hyper skill dmg. The frustration is understandable but the game is not too hard to play and titles are nothing but time consuming.
