Players definitely hate it and so do I, but on the other hand, server owners will always be interested in such engines, even if they admit it or not. If all you want is to sell this system, there's nothing to worry about.
I developed something similar - a couple of years ago, but it never attracted me to keep developing it.
Like Tryskell mentioned above, as long as your server is far from being retail, you need to nerf buffs.

Webroot was the winner last year, and still, can be seen on the second place this year. It's the smallest and fastest anti-virus out there. You can easily turn it off and add exceptions.
I'm using it since August 7th, 2016.
