Hello, I really like the idea and I'm currently debating on if I want to join or not (mostly because of time restrictions and my lack of time to post too often) 
I am an avid player of tabletops and i have even been the GM for a few D&D campaigns.

That is a good point. I'll keep that in mind, likely throwing in a natural -1 to the evasion roll.

This would be a terrible idea. The -1 would cause ties to still happen! Let the rolls stay the same but if it comes down to a tie, the attacker is in favor and still hits. That way there will never be an issue with who should win in a tie
