well its a bit too late to kick paul out, and we already took out his largest advantage (his precience), next game the suggestor should give a link, and post in their suggestion a list of equipment and abilities that the person will bring or be able to use.
and no, it is mary sue, more info here lol

so are people still disputing that paul would beat ezio?
and yeah the sheild is overpowered, its invention pretty much ended conventional warfare and made pretty much every weapon obsolete.
the only way to deactivate a sheild without it blowing up is using a static generator the size of a island, maybe someone with electricity powers MIGHT be able to, but i don't think so.
electricity would be useless (and a railgun isn't electric), since im pretty sure the shield has 0 conductivity, meaning that it would just ground out.
im pretty sure a nuke could kill a sheild yeah (although i think it would make the shield blow up), but that would also kill the island
sheer force=cant kill sheild, since it operates on a molecular level, the best you could do would be hit it hard enough to blow your fist up
and hell, i don't know if a bomb at his feet WOULD kill him, im not quite sure on how much of it a shield would stop
and na he couldn't beat aizen, yeah he could negate his hypnosis thing, but he couldn't even see him due to him being made of spirit particles (and even if he could the speed difference is just way too big), hell i don't think even a lasgun could hurt aizen
