5 Custom hero vs Waves of Evrything

Description
A map, where your custom hero\'s must fight to survive against 20 waves of enemies, all different, and finally defeat saurons apprentise, who has called himself sauron (confusing eh, i\'ll get a better name later), once and for all. Sauron has poisoned the hearts of everyone, so good fighters fight for him too. (yes, even hobbits!!!) All hero\'s start at level 4, and they have their health doubled. But that isn\'t going to make it easy. Don\'t try it one player, you will probably lose. Put the Brutal MORDOR pc in the right hand corner, and DO NOT, i repeat, DO NOT play as the waves, as it will glitch and not work. Anyway, In the words of BFME2,
\"GL, HF!\"

P.S if you have played this map, please give some constructive critisism that can be used to improve my next map. Not just \"It was rubbish, give up\"

Thanks
