You really haven't said what style of play you want other than offensive.*
Offensive to me, really describes how YOU play the champion, nothing to do with the actual champion.
There is a Goth Annie Skin with the Digital Collectors Edition, don't think you would classify Annie as hot however, you know unless you are into that.
Just pretend she isn't underage & you can consider her hot.
Though this is a rather stupid question. Check lolwiki and the full list of champs, browse through and research ones that look interesting. That's how I started out.
You can't really compare any champion directly with a wow character. They are two completely different games in just about every single way. So many people expect similarities, only to be wholly disappointed when it doesn't end up like that.
