Hear ya.
Experimented with chameleon at one time because i got fed up with reload. tried Kvatch at lvl 18.
Mobcount after drawbridge:
3 spider daedra
4 Daedroth
6 Clannfears
2 Frost atronach
1 Storm atronach
3 Fire atronach
2 Xivilai
Never finished that fight with chameleon because the results disgusted me. It was a slaughter. reloaded and used invis instead. Cast spells, dodge and invis.
Hit and run tactics.

To be honest, 100% chameleon is a rather game breaking exploit. I understand its uses, but regardless if enemies run away or not, you're still gonna kill them.
