In the meantime, I'm assuming there's already Dragon Legs and you're aiming towards a torso for fighting, which is why what I'd like you to OSRS Gold do is keep them as your primary armour, but keep a Guthan's set with you to use its special attack to heal.
So your primary armor set will not degrade and offensively-friendly (torso gives strength bonuses, unlike barrows). Keep in mind that aside from Dharok's and Verac's in specific situations the rest of Barrows set (including weapons) aren't worth the trouble.
So the top 3 options I'd suggest to you Verac's skirt/Dragon Legs together with Fighter torso, and Abyssal Dragon Whip Defender (you can have a Guthan's set that heals you as well). Torag's Plate and Legs together with Whip or Defender. It's a good defense system, but in most circumstances it's almost redundant since you don't get hit much anyways. Averac's Brassard and Skirt along with whip. The complete set can be used for specific tasks such as Kalphite queen , barrows and queens and PvP.
It's all about a collective effort. It is possible to be a superb keyer but without a equally great team, you're useless. It's possible to do 5:5 largers with at most 3 good players including yourself. It could be someone who was a rage quitter or getting lazy/not doing much.
I think having certain accessories can be very helpful. For instance, that Shadow Silk Hooded. This is not only for you but for your whole team. Since even one person who isn't experiencing it could slow down your dungeon even if you're trying to emulate a lever room but the Skeletons continue to attack those who are Non Hooded one.
I'd suggest also working to improve your stats. Not just combat , but the skills too. Because time is wasted in the event that Cheap RS 3 Gold a keyer goes through the door to find that you need to prune vines , but you're not at the necessary skills, so you'll need to call another person to do the door. Sometimes they'll forget to bring knives. This can also save time. It's for the combat side of things. I'm talking about mostly Strength/Defence. Only Strength is needed for the force bar doors and other rooms in which you require this skill. Then Defence so you can equip better armor or tank more monsters.
