You can do pretty much anything while wearing plate that you can do without. It's hot, and sweaty, and you get tired quicker, and you can't run as fast, and it's hard to see if you're wearing a full helm (which is far and away the biggest problem with heavy armour imo); but on t'other hand you're practically immune to cutting weapons. Dismounted knights in plate armour and carrying nasty weapons should by rights slaughter most infantry opponents.

Mind, I had reasonable success using DEKs a while back, so they're not totally rubbish.
