An idea to think about..
How would it be like to have default finishers based on gear?
Think about this:
-Based on type of weapon/armor
-Based on type of profession
-Based on race
A combination of all above
Examples:
A Sylvari Guardian would grow a huge oak on the downed player
An Asura Engineer would spawn multiple laser turrets around a downed player and blast him/her to smithereens
A Charr Warrior would call upon a warband to tear a downed player apart
etc
etc
It does not has to replace current finishers which can be bought, but it sure would add some fun IMO
