I already said there is an issue with agro that cause me to leave the game - until it is fixed.
You are the only one I know of on the forums that thinks
1. insta kill
2. damage avoidance
would make the assassin class (based on insta kill and damage avoidance) weaker.
The issue I have is that improper sharing of agro largely prevents play at the front of the party.
I certainly do believe insta kill on high reaper will be more powerful (in a group) than what assassin was doing before reaper (even with improper sharing of agro).
I actually play the game based on whether or not it is fun to play - for me that's at the front of the party, where there is the biggest risk vs reward.
I certainly know how to avoid agro and could do just fine in reaper. I'm guessing I would have among the least deaths because avoiding agro >> miss chance.
I guess I'm just not interested in piking and throwing down firewall crits to the extent that you seem to be.
Playing at the back of the party is the equivalent of piking for me - not interactive enough and little risk vs reward.
