Ditto on Keith. I used to do fights in armor and it is really heavy but you don't simply put it on being a newbie and go on fight. It requires lots of training, and after that you are absolutely sure what you can do and how fast, and what you can't do and how to deal with it. Full-armored knight on the ground is not a turtle, it is a machine created for fighting and killing. And gets up in seconds if not wounded (everything said here also can be said about mercenaries). About warm climate - well, adrenaline keeps you fresh and lively even when there's a whopping 40 degrees (Celsius) heat. People usually lose their concious from overheathing after the battle, not during. Padded cloth under armor (don't know how's it called in English, sorry) also helps - when wet from perspiration works like isolation. Sorry for long and not-quite-understable post, somehow my English is getting worse day by day ^^; Pic is awesome :)
