Duuuuude it'd as If you're in your own little world and not even listening, with the firebolt every three year old can throw it, but with an incendiary for example you gotta land it right at their feet. If a firebolt would ohko I'd be fine with that, if it was a direct hit, however you should take less damage when you're further away from the centre. This would make it that it's just as good or even better for the people who have got the skill to aim it correctly bit would take away the "no aim factor" and if you're not fine with that, than it means you realy don't know how to aim or you wouldn't be crying about it
