Many ones (and I am as well) just never read any manuals/helps/guides before something (or someone) will force to do this. I remember when I started my first invoker (that was my third char in CF and I was almost experienced vet, since two first chars had been made to lvl 15!) and I did not know about affinites. And I practiced hell a lot with 35 undistributed points.

That is why I think more interactive help is better. Pages of plain text are simply boring to read. Especially for those like me who are not English/USA.

The help your advice is wonderful for those who've played some (a few hours perhaps) and got very basic understanding of things and wish to know more about defences and lags.
