Answered Frost Dragons

To be honest I dont think they fully thought this update through, especially since they knew a bot nuke was in the pipeline.

I agree it does seem odd, but I think there must be something to it that we haven't thought of or don't realise the significance of. Otherwise as you rightly say, it was beyond stupid to change Frost Dragons just before the bot-nuke. (I am predicting that someone will say something along the lines of "but that's Jagex for you", to which my response would be that Jagex have shown with the bot-nuke update that they are clearly not stupid )
