HI guys my list of champs average with some goodies in there but getting owned constantly in defence and was wondering what your thoughts would be for improving my arena defence Below are the champs I am currently running ive also run skullcrusher instead of lanakis for counter ability. Im thinking dropping altan moving tayrel to lead and adding maybe kael, sunesha (although support but handy AOE as ive made her bit of a nuker as such)

any suggestions for arena offense or defence appreciated thanks
