THEA has voiced his opinion, as he is wont to do, and it's an opinion that I can understand even if I don't necessarily share it. Clearly there are solvers and setters of widely differing abilities on this site and while it's fairly easy for the newbies to learn about solving clues, from explanations to the queries they post, it's less easy to learn about setting clues, because no-one wants to stick their head above the parapet and voice a criticism. I've seen so-called cryptic clues, that are effectively nothing more than single definitions with no di, but, like everyone else, I've bitten my tongue for fear of causing this kind of upset (although when BBM2 won with a letter missing from his anagram, I was the one who pointed it out!). What we don't have is an easy and constructive way of telling someone that their clue isn't very good (preferably without sounding pompous or superior.)
Having said that, I don't think that there's anything wrong with your clue, and I've just Googled back to Clueless 15 when ab set the word ROUNDABOUT and I won with 'Ogyrrem', which certainly doesn't fit the two-element rule mentioned by THEA. Ultimately, as has been said before, it's all in fun on what has developed into a very warm and inclusive site. If you'd been around a couple of years ago you would have seen some really vitriolic posts flying back and forth, but it's the way it is now because the core posters persevered - although at times I'm sure I wasn't the only one who felt like walking away from it - and a big part of building that atmosphere is the creation of Clueless, Peer Review and the Joint Effort, all of which came about, and thrived, because WE wanted them.
So - if you're determined that you won't set Clueless, then I'll releuctantly step in, but I would urge you (and redundantelf) to reconsider.
