Do not even think of suggesting DGS as a bad clan that OSRS Gold aims to be effective, but is incredibly inefficient and hypocritical, all while trying to block anyone who is able to point this out by claiming their posts are spam. Grimy Bunyip (one of their chiefs) has also stated that he believes that Bu11seye00 is a hacker of RuneScape because he cannot imagine no other way in the way that Bu11seye00 can get floors quicker that Grimy does (which averages at more than 20 minutes). Many members of DGS have also said that they consider sub-18 minute huges are impossible regardless of video evidence against it.
I'm not trying to blow your bubble however, at 110+, there are as many who aren't able to dung as less than 110. If you're looking to become more proficient at keying, simply continue to practice it. Keying for randoms can reduce your floor time however it will also enhance your ability to key. If you're used to not needing to depend on your team more, yet are capable of doing it effectively when you have a great team and you'll be able handle situations where your team isn't perfect as you'll have become accustomed to dealing with them.
Randoms also offers you the chance to meet many new people , and to make friends with those who are adept at dung and who you can get along well with. After some time, you will have enough players who train dung to put together a group fairly easily usually with one or 2 randoms, but sometimes without any.
Personally, I play often dunk with my friends however, I prefer to do randoms, too, because I know it will be the case that there'll always (or nearly always) be random people on the internet. This means that I don't need to plan my classes with other individuals.
I'd highly recommend having 70 attack, strength defence, range, and mage prior to attempting barrows. It's not necessary, only 70 ranged mage to use an MSB or mithril bolts from Buy RuneScape Gold Zanik's C'bow. It's worked for me. However, I've seen better results today.
