I like the idea. Although, a "gun" on classic no matter the style would probably ruin the game, Classic is more of a close quaters game, not distance. As for the sword no, we have swords already no need to complicate things.
Also Yephenpeace, when I first tried era I hated it. Then I tried it again and actually played a bit and started to rlly like it. U just need to get used to it. No one would be forcing u to get it anyway. Its ur problem that u dont like it.
Only real problem with the idea is I rlly dont see it happening.
