Players, unlike monsters, do not tend to stay still. The ability to do damage from range is a huge bonus on a pvp server.
Don't underestimate Int in this case
Bare in mind, although many do not agree, I think Sigil did a fantastic job with Constitution. It provides a good bonus, but not so good that it makes anything other than a Dwarf Redundant. You will hit slightly harder with a Orc or Lesser Giant, you will nuke slightly harder with a Dark Elf.
