I like the system but yes, they should change some parts like taunting and knockdown. I think it would be better if they made the armor but with a high chance to block the effect but not 100%. And if you decrease the armor you get a higher chance until it is depleted you have 100% hit chance for the effect. So it could be possible to get some cc on the opponent even if he has like 100 magical armor (like 90% resistance).
