If you're not too concerned with the RS gold appearance of your clothes, you (are a sad homo) can get Veracs skirt to wear with torags body.. Similar torags legs, albeit higher priced and with a prayer bonuses, so you are able to use it as a slayer for those who don't wish to pray to protect prayers. Dfs is only used to tank bosses and in PVP, because drag def is much better because of the massive atk bonuses.
Similar principles apply for platelegs, but with the difference that Dragon platelegs tend to be less expensive. Now, how much does it cost to fix it (convenience of repair isn't a concern since there are NPCs within Lumbridge, Khazard, Burthorpe Void Knight Outpost as well as you could also do it in your house)?
It's about 90,000 per 15 hours. It's less if you're working in your home and actually have a medium-smithing level (50 is an example that will make it cost ~70k). Let's take a round and call that 100k, similar to how we're reducing the cost of Torag's 300k instead of 340k. 86*15=1,290, which is how many hours you'd be required to be fighting with cheap Runescape gold this (not even wearing it) before you'd spent more on it than you would for a dragon platebody.
